The Air Up There


I got the message right after playing the Wednesday afternoon concert: We leave tomorrow morning, 9:30 sharp.

The ride to Savoie took about 12 hours with the hanggliders on the roof. We left in the morning and arrived after dark. After last week's weather, I was prepared for 10 days of sitting around in the cabin. But the weather forecast was flyable so we set our alarms and planned to be at the landing field for pre-flight briefing at 8.

6.30AM: Peter and I wake up frozen in our un-insulated cabin. There was frost on the ground outside our window and condensate on our breath. Peter threw on all 4 stove burners and started fanning the heat into the room. Slowly over the next hour we brought ourselves back to comfort.

8AM: We rendez-vous with the rest of our party at the landing field. One instructor, one assistant-instructor, one very experienced student, 2 mid-level students, one 2nd timer, and one fool who was doing this for the first time. We got our flight plan, learned the terminology that Peter would use over the radio, the names of the different corners of the landing field, the protocol for shedding altitude over the landing field, etc. We got back in our cars and started the drive up the mountain. I had both the eagerness to make sure I got to fly, and the nervousness of my first mountain flight. Was I actually going to be soaring a couple thousand feet above ground in a few hours? I had proved myself on the training hill, but it had been 10 days since I had touched a glider and I wasn’t going to get a practice run.

Peter had explained during the drive down why we chose this site: "Its the safest place I know. The takeoff is a gradual slope. First grass. Then bushes. Then trees. Plenty of time to turn back. Plenty of barriers that you can only clear if you have enough lift to fly over them.” So while I was nervous, I felt good about the circumstances.
The drive up the mountain was 20 minutes long, through winding narrow roads, first passing through the picturesque hillside village of Chindrieux, old stone walls and houses with flowers growing out of them, then up through forest and rising snow levels.

We got to the take-off site, which was entirely covered in snow.

He kicked at the icy snow by the start of the runway and stood there for a minute or two, deep in thought. Finally he looked at me. "There is another place you can take off from, but its impressive. We will go and you will tell me if you want to take off from there." Peter's English has a few idiosyncrasies that I've gotten to know over the course of my training. When he says impressive, he means scary as all hell.

The trompe-plein is a wooden platform, about 30 feet long. The first 15 feet are flat. The rest of it slopes down at a 40 degree angle and ends abruptly over the rustic countryside half a mile below us. Its as though someone had tried to build a wide wooden slide down a 2000ft mountain, but had given up after the first few segments.


“I want to do it,” said Ilsa, one of the intermediate students. I held my tongue, hoping that the next half hour of building-up the gliders would give me the chance to build-up some courage as well.

I built-up my glider in a haze of fear, adrenaline, and stupidity, and made Stephan, the assistant instructor, inspect it with all his might. Peter’s words echoed in my head “Its an incredibly safe takeoff, but its impressive”. Impressive is the understatement of the year. I said a shema.

The glider is a flying machine. It wants to fly. You run off a something like the trompeplein with a glider and a headwind and it should fly. All my theory told me this. And all my animal instincts told me that to run off a ramp into nothingness was sheer madness. I would only have once chance to do this right. I was betting that I could hold 80 pounds of wind-catching metal and fabric steady and run full-speed, without tripping or tipping, off the scariest ledge I’d ever seen. No practice runs, no do-overs. One straight run with full stakes.

I thought that watching Ilsa’s take off would reassure me, but it just did the opposite. One moment she was standing there, another moment hurtling into steepness, and within seconds she was a football field away from us, hanging free with emptiness on every side. I said another shema.

My turn came. I stood with my toes at the end of the flat segment. Before I could run I’d have to lean forward and start to fall, giving the glider some momentum so that it would stay with me. Once I did that there was no turning back and anything I did to fight gravity would only endanger me. Speed is safety. Speed is safety. Speed is safety. The wind stabilized. Stephan gave me the go-ahead. “When you feel ready, you can start running.” And friends, I ran.

I don’t remember anything between the start of my run and the moment, a few seconds later, when my glider stabilized in the air. But on that day, when I took my run into nothingness, the somethingness I found afterwards was completely different from what I expected. After all that adrenaline and all that buildup, I was just hanging peacefully. The air was so calm and stable that I felt as though I were simply attached to a giant crane that was slowly lowering me to my destination. Was I really flying? My glider tends to nose-up and stall, and because the ground was falling away from me rapidly I had the feeling that I was in a never-ending stall. Up and down are not entirely clear at first. I pulled in and tried to keep the nose down, and keep a steady course for all I was worth. My hands nearly froze onto the metal bars of the glider frame, but I wasn’t about to let go. Peter stayed with me on radio contact the whole time, even if just to say, “well, there’s not really much to say, you’re doing fine”. I landed alive and surprised at how ordinary I felt, having just run off of a cliff.

The most surreal part of the day was yet to come. We packed up our gliders. We left the landing field. And we drove to the supermarket. In less than an hour I went from hanging free 2000 feet above ground to standing in an aisle of canned goods choosing between brands of tuna. Life goes on?

For the past few days its been a dependable routine: we wake up, get warm, eat, hit the landing field, and then drive up to the take-off. If the wind looks good (and it always has), we haul the gliders from the cars, assemble them (I’ve gotten down to 25 minutes for assembly, 35-40 to be ready for take-off), suit up, and take-off. There are pre-flight inspections, and if you’ve made any mistakes, you owe the instructor a bottle of wine. I’d gladly buy my life for the price of a bottle, but so far, no problems. At the landing field, we disassemble, load the cars, go back to the campground, and eat lunch, which always seems to involve fresh bread, cheeses, and wine. I seem to have taken the attitude of “eat well today because who knows about tomorrow.” In the afternoon we repeat the flying process, and then at night we repeat the eating process.

Its been 2 days and 5 flights since that first run into nothingness. Renzo, the 2nd-timer who wasn’t up to the trompe-plein spent some time salting and shoveling the original takeoff while we were at the supermarket. So the rest of my takeoffs have been a bit less dramatic than that first day (the second and third take-offs were still pretty adrenalized).

I’ve been improving loads over the past few days. On my first flight, I basically just survived. On my second flight, I leveled-off my 180-turns at the landing field, which had been too extreme. On my third flight I learned to use the foot-bar (a small rod that hangs down from your harness -- you can rest the soles of your feet on it so that you can lie horizontally instead of hanging with your legs dangling in the air – it involves some extra maneuvers to get into it mid-air, and to get out of it before landing, not to mention the psychological factor of doing a running take-off with it banging against your heels). On the fourth flight I worked on my steering sensitivity, reacting quicker and using less force. Peter let me have control for most of it. On my fifth flight, I had some turbulence from thermals (rising pockets of air) and was able to steer into them and gain a bit of altitude on my way to the landing field. Thermals are invisible, but you know they’re there because all of a sudden one wingtip rises throws you into a turn. Thermals push you away, but if you fight the turn early and get the glider level, you can slip into them and get an upward boost (at least this is what I’ve found). Feels almost like a game. In more advanced stages you actually learn to do circles inside of them and ride them high into the sky.

I think flight #4 was my favorite. It was yesterday evening, a bit before sunset. By the time we had our gliders built, the wind had shifted to a gentle tailwind.

Wind follows the contours of the slope. If the wind comes from behind you on a downward slope, it flows down at the angle of the hill. Because the glider flies at a 15 degree downward angle relative to the air, its physically impossible to do a running take-off in a tailwind. You’d have to be able to run at an angle 15 degrees steeper than the ground you’re standing on.

Stephan was betting that with the setting sun the tailwind would only grow stronger. I expected we would be disassembling and driving downhill, but Peter radioed up that because I was underweight for my glider, I could try to take-off if we got a moment of feeble headwind. I took my position on the runway and waited some more, watching the 4 wind-flags scattered throughout the take-off area, all of which were doing different things. Finally they harmonized for a minute, all pointing with the laziest little inkling uphill. Stephan said go, I ran, and all of a sudden I was in the air. Once you’re in the air, it doesn’t matter whether there’s a head or tailwind. You’re flying either way, and in the warmth of the setting sun, I felt as though I had just escaped from the glum disappointment on the take-off hill into complete and utter freedom. No adrenalized buildup. No fear. Just a hopeful wait, a moment’s run, and the air rushing by me. Peter radioed up that I was on my own until the landing field. “You can do smart things, stupid things, I won’t say anything.” I took a few extra turns to get a nice view of the lake and mountains in the evening light. The air was calm enough that I could look down and really feel the bird’s-eye view over the land below. The more you can do that, the more you feel like you’re really flying.

Well, I think I’m hooked. It took a bit of time to get over the fact that you don’t quite feel like superman, zooming around in any direction you choose. But once you’re past that, the little joys of flight seem to grow steadily.

Tonight is the first evening without flying. The wind has picked up and the weather seems to be changing. Peter’s guess is no flying tomorrow. His hope is for flights the day after. But after 5 back-to-back flights, I’m almost happy to have a little break to relax, soak it all in, and condense my experiences here. Hopefully the weather will have me back in the air before long.

Sorry voor dit gejojo

An excerpt from the text of the latest e-mail from my hanggliding school director: "Sorry voor dit gejojo". Which as far as I can figure, means "sorry for all this yoyo-ing." I'm not too annoyed at the 'gejojo' (cheyoyo), after all, weather is a finicky thing. But its certainly set the tone for a yoyo-ish past few days:

The hanggliding news feed:
5 days ago: We'll be driving up this weekend (I find a ride leaving Sunday night)

4 days ago: NE winds and low temperatures. No flying until Wednesday at least. (I volunteer to play the Sunday afternoon concert in Mechelen).

3 days ago: Anticyclone activity over the gulf of Biskaye. Conditions will be cold but flyable. We start Monday.

2 days ago: We are still going, but you will need snow tires to get to the campsite, and our water may be cut for up to three days. Monday and Wednesday look flyable. (My ride cancels. Peter my director offers a ride for Sunday morning, before the concert that I'm supposed to be playing. I wonder if no water means no heat either.)

1 day ago: The road is inaccessible, even with snow chains. Postponed until Thursday.

Last night, 7pm: Someone down there says the road is actually accessible. Peter leaves 10am, but I still have a concert at 3pm. I send out an e-mail looking for later rides.

Last night, 2am: I check e-mail. No ride offers. I set my alarm for 7:30am, planning to double check for rides, find out if anyone can replace me for carillon, and if necessary, pack, arrange a replacement, and be ready to leave at 10am

This morning, 7:30am. I get a list of people to call as replacements. Do I really want to call these people early on Easter Sunday and ask for a day-of favor? I look into alternate ways to get to the site. I get a phone number of someone who's driving down. I weigh options.

This morning, 9:00am, 1 hour before my ride leaves: Actually the road is inaccessible. The guy who said it was open was mistaken. Trip postponed until Friday at least.


Well, here I am, underslept but too awake to go back to bed. I've got another 6 days in Mechelen. In some sense that's a good thing, I was really feeling like a 2 week break was a bit too long given where my studies are at. But in another sense, it means fewer shots at good flying days. I really do hope I get to fly this time around.



In other news:
Monday I went with Geert to Middelburg, Netherlands, where he has a student, and where he is working to start up a master's program in carillon. We both got a lesson on Lange Jan, the city tower, then hit a bar for a couple bottles of wine, and loads of fried food. This was a really wonderful trip. I like the format of 2-person lessons. Watching someone else receive instruction, and seeing the process without being distracted by trying to implement corrections, etc... can be just as educational as having the lesson yourself. And playing with others is just much more inspiring. BTW she plays better, in my opinion, than anyone else who's here with me at Mechelen, and she's been studying for only 3 years. Convinced me that I should be working harder / smarter. And 2 bottles of wine plus convo with two talented and driven folks in the same discipline as me (rare) makes for a spectacular evening.

I'm moving past my initial struggles from the fall where I would worry about whether I want to focus more on learning from Eddy or Geert. At first, they seemed to be radically different. But I think they're complimentary. Different styles, but there's enough common ground in their concepts of musicality that I don't feel torn by studying with both. One difference between Geert and Eddy is that Geert teaches conductor style and Eddy teaches corrector style. With Eddy, I play something, we talk about it, and I try it again, repeating until we get to a performance that we both agree is good. This means I learn how to find my way to the right place. Geert does a lot of conducting and coaching while you're playing, which means I get the immediate experience of hurtling through the piece as a master would. It leaves a slight disorienting aftertaste, the feeling of "how did I do that again?" and "Can I remember enough to get back on my own?" but its also great to have direct access to the feeling of a stellar performance, and its my hope that over time, these experiences sink in, they integrate such that you can find your way back.


In other other news:
I got a surprise visit from Mike Lee, a high school friend, who got posted to London for a month for work. Way to go Mike! Last night we were up until 2, playing Settlers of Catan with Ren from downstairs, drinking Grimbergen (high quality Belgian brown beer), and eating 'frituur', fries and assorted other fried goods, in order to introduce Mike the real Belgian culinary tradition (2 nights ago we did the classier culinary tour -- chocolate, mussels, beer, restaurant-style fries, and waffles). Today we're hitting Rombouts, and if I can stay awake, I'll give a good concert and we'll check out the view from up top. Remember, this can be yours too...



And because I try for the multimedia blog experience:
Here's a clip from a Romanian Jazz concert in Brussels that I went to with BAEF fellows. The band-leader played cimbala, something like an eastern-european-sounding hammered dulcimer. But the star of the night was definitely the guest drummer who joined them for the last few numbers, apparently a rock legend in Romania. Think skills of a seasoned veteran with the enthusiasm of an three-year-old who just discovered the neighbor's drum set. Anybody else reminded of Animal from the Muppets?

Going to Chiendrieux

After a long period of uncertainty going down to the wire, I logged the necessary training and been approved by my hanggliding instructor for mountain flights. We leave in 8 days, and will be taking over some cabins in France by the mountains (Chiendrieux) and running off cliffs and stuff. Should be fun. I have some video and pics of me flying, but its a wingtip camera aimed at me, so you don't really see the view or the drop -- just me hanging there. Anyways, you can check it out to get a feel for what take off and landing looks like at least.



Its been a busy week or so -- I've been distracted from practice by two projects -- one was making sure I qualified for mountain flights -- which means yesterday and today were a double header of 'the triathaon': biking to the training hill, (45min - 1hr), flying down it and then hauling 80lbs of metal back up the hill a bunch of times, then climbing up a carillon tower or two (today was the school trip to the carillons of Leuven,
which I joined midway after a morning on the hill) -- several hours of sustained activity with intense sprint-like bursts scattered throughout. I'm just about ready to collapse into a deep slumber. The other project was making a 5-minute purim-related film for a contest that only had one other entry and offers a nice cash prize (a friend who works for the sponsoring org tipped me off). A 5 minute film turns out to be over 100 takes and 15-20 hours of work, at least for a newbie like me. Its not particularly high quality, but it just has to be better than the other guy's.
Carillon design has been faltering a bit, I'm starting to realize that sound production will be tricky and I haven't yet mastered how to build acoustic resonators to best amplify the sound of the tone bars. I started this project figuring I'd do some clever stuff with the mechanics of play and then add on some tone bars to make it sound, but if I actually want a reasonable instrument to support my musical development, the sound-production system looks to be the hardest part right now. Hopefully I'll have a breakthrough sometime soon, because I'll probably need a good 2 months to build it once the designs are in place.
I think thats about it for now... having finished the film and the qualifying for mountain flights, I have a whole week ahead of me to make some progress on practice, carillon building, and getting my summer organized. With two trips into Brussels mixed in, one for a fellowship get-together, one for a megillah reading, it should be an active, but hopefully manageable week.

Foundries and other Business

For your sake and mine, I'm gonna keep it short.
Things are rocking out here. This past week has seen me
-playing carillon twice in St. Rombouts tower (nearly 1000 stairs in a 3-day period),
-in a wood-shop trying to learn how to make a practice carillon sound good,
-in a practice room dissecting a well-made practice carillon for some insights (turns out I missed a decimal point in my calculations and the required air spaces that I need to fit into my design are an order of magnitude smaller than expected -- very good news),
-in an industrial bell-foundry taking in the sites and seeing if I can get any additional insights,
-in a classroom drinking great wine as part of an apparent nascent tradition of toasting birthdays,
and my favorite,
-50 feet in the air strapped to a hang-glider (and subsequently 0 feet covered in mud).

I've been engaging in musical practice, physical activity, textual and hands-on research, physics and engineering, and good food and drink. I think that having my thesis stuff in the mix is rounding out the experience nicely -- pulling my math-physics brain back into the mix, and giving me a really interesting puzzle to work ong so I don't have to invent problems to get my fix. Dark is coming later, the city is waking up, and things are looking up. I've even maybe got some travel on the distant horizon!

Some pics from the foundry:

Experimenting with glass bells

Fully tuned and polished

Coating the outside of a sand bell to make the outer mold for the casting process

Cores (inner molds) waiting in the pit. Notice the chute on the far wall -- it carries 1100C molten bronze. The casting is done in a pit so that in case of an accident you don't get liquid bronze pouring across the floor. Then the pit is filled with sand to let the bells cool slowly over a period of several days.

Strickelboards giving the inner and outer profiles of the bell. Used for shaping molds on a turning table. The invention of the strickelboard (500-600 years) ago totally changed the process of bellmaking. These used to be passed down from father to son, keeping alive successful bell profiles through the generations.
