I can't believe the abuse of
that balloon bad enough people touching it, but grabbing it and
pulling on it UG there are better ways to do windy launches.

It exceeded the burst calculations by about 10,000'. Zack On Sat, May 1, 2021, 10:11 PM Joe WB9SBD <nss@...> wrote:

Wow...it was in the next county before it cleared 1000 feet !!!
I have a rule which I have violated many times. If the wind is strong enough to blow the hat off of my head, it is too windy for a balloon launch.

My Hold back method still
works great.

My rule is never launch in winds faster than you can run. Since age is catching up with me Ive been experimenting with
de-reelers (with some success). Steve On 02/05/2021 05:39, Bill Brown via

What do you US guys call that style of launch - I've heard "hail mary" in the past - is that it? Not sure why? I guess that's a running hail mary? Steve G8KHW On 02/05/2021 14:30, Michael wrote:

All those bare hands, exposed finger nails, and watches on arms… its amazing it got into the air at all. Great launch!

This is my third ever flight in 1989 with surface winds over 20 knots. You'd think I would learn from this not to launch in high winds, but I didn't :-)

We almost took out the camera woman as the payload smashed into the field and bounced over her head.
That payload with its original lithium D-cell SAFT batteries still operates today when I power it up for demos after 33 years.
This is how an ideal launch should look like, I don't get these kind of launches very often:

When we were launching, everyone who was close to the balloon wore cotton or latex gloves. That video reminded me of our first launch. SUPER windy day in SE Alberta and not enough fill! Terrible combination! Learned a ton from that failed launch. You folks certainly had enough fill. Thanks for sharing! Tony SABLE On Sat, May 1, 2021 at 7:50 PM Zack Clobes W0ZC <zclobes@...> wrote:

We had one like that once. When we let it go it took off with such a jerk it broke the line under the parachute. So we lost the balloon and the parachute. None of the payloads left the ground. We now do tethered launches, where we have a string on the balloon until all the payloads are off the ground. The String goes through a loop and we have two people holding it. One lets go of the string and it takes off. Leaving the string with the other person. And we do not launch in such wind.

Thats our what we call out Hold Back line launch. we have been doing that since the 1980's. We launch is winds like that with 2 people, smooth and effortless. we even use the hold back even if the wind is only 5 MPh. Absolutely zero g forces on lines, payloads, anything smooth launch even if the wind is huge! Joe WB9SBD On 5/2/2021 10:21 AM, AE5IB (Kip)

We've used gloves in the past, but I can't correlate any performance trends with or without. My gut tells me that skin oils take far more than the typical 90 minutes to become a factor. Jewelry is another story, and I'd warned the handlers to check for sharp objects. As it turned out we had a bunch of first timers watching and as we got outside we needed all hands on deck... Hence some of the extra drama. As for fill, I knew we were going to be struggling with the winds today so I shed down to minimum payload (1kg), 800g balloon, and dumped the entire bottle into the thing. Fortunately the tower cleared us as soon as we were in position and I called for a very quick 3-2-1 release. Zack On Sun, May 2, 2021, 10:18 AM Tony Rafaat <trafaat@...> wrote:

I've done the string tether in the past. Some of you at a GPSL roughly 10 years ago at this very airport might remember my tethers getting looped around the load line, causing a friction burn. It cut the balloon away letting the parachute float back to the ground. Not cool. Zack On Sun, May 2, 2021, 10:21 AM AE5IB (Kip) <kiptonm@...> wrote:

That's why you have the loop
in the line, the tether never even gets close to the support
line and if it cuts through the loop Great!
