Sorry I haven't been into this email account since Friday - super busy
weekend (wedding anniversary, trip into Brooklyn, and I set up a camera
I should have mentioned in my original post email that I was unable to
attend on Saturday . I've had some ideas about how to steer the decent, but
I think that the Styrofoam glider idea is the best.
It allows for a fast decent and that minimizes the effect of wind. Steering
a slower moving parachute is easier, but wind will still carry it further I
think if the decent is slower.
Also, instead of an actively controlled decent, the glider could just be
fixed for a spiral decent. Is there a maximum decent rate allowed by law?

Thanks for doing the course prediction.
Wow. It looks like that balloon course was straight down. (south)
I don't like the exact landing spot, but it seems like it's surrounded by
farmland, so if the predictions are off a bit, it could land in a good
It's also *kinda* close to Airhaven Airport.
If it goes off course in that direction it could be a serious problem.
Maybe there's a better launch location for this weather pattern.
For the record, I'm available Saturday if there's a chase team ready to go.
Helium tanks, a station-wagon, a boat and a weather balloon are packed and
Sean: If you're ready+willing to go tomorrow, please send me your phone
number. (with a direct e-mail, not on the list)
We'd need Joe (and others) to chime in here too.
Since I haven't seen anybody else respond on the list, I assume that we
can't launch this weekend.
If the launch situation changes, someone please give me a call.
