The story

One of the last 747SPs flying anywhere — the short, stubby long-ranger Boeing built in tiny numbers in the 1970s. Pratt & Whitney Canada flies this one out of Montreal as an engine testbed, keeping one of aviation's rarest silhouettes in the air decades after the type vanished from airlines.

Fun fact

Only 45 747SPs were ever built; you can count the ones still flying on one hand — and this is one of them.
