It was a plane..now. RV....

727/737 size airplanes are called "single-aisle" type. "Jumbo jets"are two aisle airplanes - the 767 being at the smaller end and the A-380 at the large end. It's hard to tell from the picture whether it's the full length of a 727.

After viewing the video, I believe it was originally a 727-100 from the late 1960s.
