Does anyone know of an instance where a pilot goes to loop, but instead of pulling up to do it, he pushes down.  I've never seen it done, nor heard of it being attempted.  They did it on the magic schoolbus, but Im not sure if it's possiblein real life.

Like an 'inside' loop, an 'outside' loop' describes a complete circle.  One starts with a pull, the other a push which causes negative G's and a lot of dirt in your hair.  Too much for any normal category plane whereas most of them have no trouble with the inside loop.

I know the difference between an inside & outside loop. What I meant was that I've always referred to the half outside loop as a bunt. The "English" prefix apparently comes from the manoeuvre first being performed at the Royal Aircraft Establishment at Farnborough. James Doolittle was the first person to complete a full outside loop in a Curtiss P-1B over McCook Field, Dayton, Ohio in May 1927. http://books.google.co.uk/books?id=kc3aoLOiGVkC&pg=PA47&dq=doolittle+outside+loo...
