Triple Deck Auto Transport Plane Cutaway, 1952
A lovely 3-color cutaway by Popular Science stalwart, technical illustrator Ray Piotch, of the Blackburn Universal Freighter (“BUF”).
The BUF had two lower freight decks that could accommodate 6-8 autos, depending on size, and an upper deck for 42 passengers.
This hulking beast wasn’t known for its speed, though, reaching a maximum of 180 miles an hour.
