Two airplanes are positioned next to each other on the
launching pad, facing opposite directions. A strong steel
cable connects the pair. Both planes power up their
engines simultaneously, causing the whole thing to spin
up into the air like an out-of-control carousel. Once
they reach sufficient
altitude, the cable is released and
both airplanes proceed in opposite directions.
Landing is accomplished by having the two planes make
a tighter and tighter spiral until they're close enough
that one pilot can hook the other plane, rodeo-style,
and then reversing the process for taking off.

||With enough wheel rotation it's a for sure. See a similar "spinning launch" method by searching Google for:
discus launch AND glider OR "flying wing."
||This is probably the most perfect "Who needs a
runway? Every airplane can be..." concept yet to
appear on these hollowed pages.
||I think this could actually work, especially with computer controls, except for the landing part.
||The link indicates that the occupants would only feel a relaxing 2.2 Gs if the steel cable were 100 meters long and the speed were 100 miles per hour.
||Were you allowing for the length of the wings -
assuming the tether is on the wingtips?
||Nope. Hard to do since I don't know what plane we are talking about.
||If it is a really big plane, like a 747, you end up with 30 meters of wing at each end, and only 40 meters of cable. Of course, a 747 would not be able to take off at that low a speed.
