Some of the guys arranged an escort for it and are shown in the videos:http://www.youtube.com/watch?v=S2x1EaXqDsA There are also some other videos from German TV when they visited a couple of years ago: http://www.youtube.com/watch?v=dv6T1...eature=related Hi Orval; Had a great and funny experience with the Blimp once. Don't know if you've ever read this but I've pasted the story in below; The following "aerobatic conference" on the Goodyear blimp took place during a break in the preflight brief with the Blue Angels at Reading in 74, after we all watched the thing fly past the office window and Jerry Tucker announced, "Hey look, ain't THAT a gas?" It was decided by all present that some initial modifications should be made before aerobatics were attempted in this vehicle. First of all, Ps or ability to convert energy had to be looked at seriously. We all agreed that in it's existing configuration, the blimp has the aerodynamic properties of a brontosaurus. Tony Less agreed with me that this might just be a bad situation for akro, although both of us agreed that it's ok if you're a brontosaurus. I suggested we use a belt that we could put around the blimp in the middle; sort of on a ratchet that could be tightened up by the crew inside the gondola. The result would pinch it in at the middle so we could utilize the advantages of the area rule. This just might reduce some drag if we could only get the speed up a bit more. Getting the speed up was solved when someone suggested that at the moment of takeoff, ground crew could run around to the backside and poke the blimp with a fork right at the exact center between the fins. Now the crew would have to be specially trained for aerobatics. Vertical maneuvers especially would require constant coordination by the crew. In a loop for instance, all crew would have to wear magnetic boots and stand on metal plates attached to the floor. As the blimp went inverted at the top, the Captain would have to shout the command,"NOW"...and all crew would instantly extend their arms to hold the pillows in place on the sofa. Something would have to be done about the roll rate. We all decided it was totally unacceptable. Air show time restraints really conflicted with the 13 days required to do a slow roll, although we all thought we could live with the high speed pass, IF the announcer was required to make the following announcement."Ladies and gentlemen, the Goodyear blimp is now beginning a high speed pass over the field. Those of you at lunch at the cafateria have two hours to return to the flight line before the pass has been completed...Thank you!" The choice of maneuvers was unanimous. The routine should begin with two exciting and crowd pleasing "whale rolls". This would get the crowd really up and running. Then, a turn around,[while the Thunderbirds take off, do their show, and return] into the "poop loop". Finally, after lunch, the loop is completed, and about 3PM, we have the finale!!! The death defying pull into a left "bagover", followed by an "inverted hissout!!!" After careful consideration by everyone present, we all decided to keep this to ourselves. There is only so much excitement an airshow crowd can stand, and we felt that this might give Goodyear an unfair advantage over the Blues. :-) |
