How does one launch a blimp? The answer is "slowly"…blimps do nothing rapidly. I became aware of that years ago when The Ohio State University Airport was visited on occasion by the Goodyear blimps that covered major sports events in the Columbus area. When the flight schedule permitted, the OSU Department of Aviation folks were welcomed aboard for a low-altitude, low-airspeed tour of the city. That blimp ride was a first-time experience for me and given my zero knowledge of airship operations I wondered how this bagful of helium would get off the ground.
The neutrally bouyant blimp was resting lightly on its single wheel and anchored, so to speak, by the ground crew holding the mooring lines attached to the nose. There was a hand rail running completely around the bottom of the gondola and when the pilot was ready the launch crew lifted the blimp to arms' length then pulled it down briskly.
The wheel strut compressed when it contacted the ground and the gas bag sagged a bit around the gondola, resulting in an upward rebound (Newton's third law of motion at work—equal and opposite reaction) whereupon the pilot opened the throttles and the blimp climbed away…an AVTO (Almost Vertical Takeoff). The entire procedure took place in graceful, ponderous slow motion.
