fair points made by all. i'd have to agree it'd be a bad plan to want to fly outside the envelope. Although to be fair the barrel roll by Tex Johnston on the prototype 707 whilst (what i only assume must be) outside the normal envelope was still impressive. Oh can i get a beer aswell for pushin scroggs up to those 2000 posts.
Oh and i know a mate at uni doing a phd developing pilotless civilian transporter. He's workin with a major aircraft company, although they'll only use some ideas to improve further
piloted aircraft and not actually make a pilotless aircraft (yet).
