It actually looks like the B47 that featured in the IMAX film "Choppers" (or something similarly named.) Gentleman pilot in the film is doing some equally "adventurous" manoeuvres.
Jetflite - I think the next frame is probably the pilot calling the aircraft owner:
(PILOT) Bill I can't seem to open the pilots door......
(OWNER) Why's that Gary?
(PILOT) There is a helicopter on top of it.
