YouTube - Boeing 720 Demo

Sources say there were about 65 720s and 89 720Bs produced. NW used to bring its 720s into ATL when I was a kid and they were home sick angels on climb out. Eastern also operated some 720s and they were considered real hot rods by the pilots. United, Continental and Western also flew this short range version of the 707.

The stop-action video starts with the 'monster' chopping off the cockpit. Not pretty..
