Thanks for that head's up, Tim! I has assumed that the prohibition on cell phones aboard commercial aircraft had to do with EMC issues with comm/nav systems....

I'm gone the weekend of 9 - 16 July and the first two weekends in August aren't too good either. Non-holiday weekends tend to work better for us, but I don't...
Hi Mark, Well, I guess early congratulations are in order! Unfortunately, June and July are jam-packed as usual for EOSS. We have Space Grant flights ...

We've experimented with this concept a little. We were successfully able to glue an eye-bolt to the top of the "MAIN" balloon and attach the "BOOSTER" above....
What kind of glue? For a duration flight, it would seem the glue would affect the balloon's longevity. I wonder if the "booster" could be flown right next to...
Regarding balloons bouncing off of each other, see the image at http://www.amrad.pt/lancamento_cinelsat2.php. This configuration flew for 15hrs+ (15hrs is all...

I'm copying Don's repeater very roughly on a discone in the attic here in Hutchinson, KS. The glue was some 3M stuff that was kind of tricky to get a hold of....
I think we're down to one of the three summer holiday weekends for our new GPSL 2005 date - Memorial Day, 4th of July, or Labor Day. I'm a little partial to...
Hi Ralph, WE've tried pairs of balloons in order to achieve a controlled, moderate descent rate. Theoretically, the "ballast" balloon would also serve as a ...

As long as we can do a launch that I have vacation time for, I'd be happy to help with the chase and recovery. I like the latex balloon method not only...
I would suggest a goal of a 10-12 hr flight (dawn-dusk) for our first attempt. This would lend itself to a long day but could be handled with the 'normal'...
I haven't kept up with the thread, so this may have been covered. One point I haven't seen covered yet is; it is my understanding the latex balloons are...
... Ralph: I've always really liked the MAIN and BOOSTER concept, but I think a long flight as you describe may be very hard to obtain. One out-house data...
Ralph: Respectfully, I think you're off a bit on your "10X" cost increase estimate for the jump from latex to poly. I've been quoted $200 to $300 for a 3000...
I've done several 2 and 3 balloon flights some years ago.....the 3 balloon flight was interesting in that 2 of the balloons burst but one remained and provided...

A flight during Field Day would be interesting. It's during vacation, so it's convienent. The chase of 240 miles is not excessive for a summer vacation drive....
I don't remember if it was after I got back from GPSL 2004 or our next flight that I ran a prediction with a 12 hr float @ 80,000. The payload would've ended...
If the long duration flight takes to the air, I have a light weight (2 pound) HF beacon package. It can send a PSK-31 message, 300 bps FSK APRS message, or...
