This is a reworked and reuploaded version of the original video.

Hello! :D

In today's episode, we look at the history of perhaps the most obscure variant of the Boeing 747, the Special Performance or SP. While its bizarre proportions may come across as comedic, the airliner was actually built to fill a gap in Boeing's line-up during the 1970s, but was ultimately a victim of ever-changing circumstances and external economic factors.
