Ok, it would not be practical for a family flyer - but is anyone currently
experimenting with a rubber band powered aircraft? Any websites regarding
how much power is available, and for what duration?

I found some information on rubber band powered aircraft in the 1800's, but
few details. Seems like an ultralight ship ought to be able to get off the
ground - and that is what flying is all about.

Wonder what the distance record is for a rubber band powered aircraft?

Someone must have done it, because in some of the old movies the pilot yells
out "wind 'er up" just before takeoff.
