A B-26 that has been converted with large clear sheets of special plastic on the nose and side bulges are used by some groups. For some highly commercial use a Lear Jet from the Clay Lacy company has a periscope camera that when lowered from the bottom of the aircraft has a 360 degree view. I've been on DC9 and B727 with special clearance when Clay's plane and the target (ours) would perform a dual takeoff on the same runway. Our plane would stay nose on towards his tail for some spectacular take offs shots. Then sometimes he would pull to the side and slow while the target would climb parallel and pan past. Utterly spectaular footage. The climb past was necessary if the contractor wanted the audience to the ID
/color scheme as from head on identification is impossible to casual audience. Take off from some airports like COS
provides great backgrounds.
