In the early 1960s there was a resurgence in trimotor (or trijets) aircraft. Mainly stemming from operating limitations placed on twin-engine aircraft relating to loss of an engine. This led British Aerospace to develop the BAC HS.121 Trident, while Boeing put together the 727 for the mid-tier market and Douglas and Lockheed moved on the wide-body arena. Better, more reliable and efficient jet engines eventually negated all of these designs. Here we see a Braniff International 727-100 (727-062) towed to a hangar at an undisclosed location.
