I recall, now, an airplane that can change heading by 180 degrees within
one wingspan.

It is a DC-3 that is mounted on a pedestal at Whitehorse, Yukon,
airport. It is on a support that permits it to windcock, and it does,
even in a slight breeze.

And it needs no more space that one wingspan to do a 180 or even a 360!
