I always figured one of those things would just bounce off of whatever they hit!

Did it pop like a balloon and zip across they sky before going flat and landing? That would have been a ride!
Speaking of rides, when I was 8 years old my Dad was able to procure a trip on the Goodyear Airship Columbia out here at their airship operations in Southern California. He scooped all 5 of us kids from school on a moments notice and we were up on an aerial tour of Long Beach, the Naval Shipyard, the old Long Beach Pike Roller Coaster and back to Carson, CA where they maintain the airship. It was the absolute first time I had EVER been in the air in anything and it actually scared the hell out of me! Back in that day the "blimp" which was one of only 3 in the USA was a noisy SOB and when they took off the ground crew of about a dozen burly guys would bounce it off the ground and it would then pitch up to a VERY steep angle, power up full throttle, and power darned near straight up making a ton of noise. I remember being petrified but once we were straight and level the view was pretty cool. I have to find those old 16mm films my Dad took of that trip, heck, it was only 35 years ago.
Nowadays there's a zillion airships around, anybody been on one?
