I wrote an email to Jonathan Trappe (clusterballooner extraordinaire) about the 283 balloons he used on the clustered house flight and here is his very informative (and quick response!) reply:
"The cells we used for the house were one-time use. They break down in the sun very quickly, and there is no easy way to deflate them. A couple--maybe. But, the gas does not come out easily. They took 12+ hours to inflate; it would take longer than that to deflate them-- and in the end, you'd have cells of questionable airworthiness.
The balloons took us into the sky; but, it doesn't end well for them. The ones that survived the flight were popped upon landing~
Tracy Barnes built a personal airship not too long ago. Built a hangar for it and everything. Now the hangar is a balloon factory, for polyethelene balloons. Gondola was wicker-- with a stained glass window in the back. Photo of the gondola attached.
Let's see-- Dan Nachbar built a thermal airship-- nice coverage in two issues of BALLOONING Journal~
Thx!"
