The regs seem to simply require experience while'towing a glider with an aircraft' and the U.S.regs don't seem to care what kind of aircraftis used. Tow with a blimp? Don'tthose things go something like maybe twentyknots tops? While towing gliders I've been quite concernedabout my 'noodle.' Yes I've been concernedabout catching on a runway light, rope in theprop during taxi, etc. But the idea of therope snapping back and wrapping the elevatoror rudder in flight has been a concern both as a towpilot and as a glider pilot. Prettyremote possibility, but a good reason fora nice weak link at the end of the towrope.Towing in a helicopter? My goodness! Thiswould REALLY scare me. Towrope in the rotor blades? Yikes! Did they have somethingweighty on the end of the towrope?Mark Boyd
