The maintenance >folks would be incredibly irritated by such a monster! I have a reference that mentions that one version of the De Havilland Trident was built with two different types of engines. (The Trident was a three-engined plane configured the same as a 727.) Apparently, De Havilland wanted to create a version with higher takeoff weights, so they took the Trident Three, which used RR Spey engines, and perched a fourth "booster" engine on top of the center engine, drawing air from a takeoff on the S-tunnel. The fourth engine was an RR engine called the RB162; it was a 5,250 lb. thrust engine. (I'm guessing that it was a small military engine.) Apparently, it was only used for takeoff, and was shut down after reaching altitude. If I'm reading the book right (it's a little confusing), this was called the Super Trident 3B, and only two were ordered, both by CAAC. There is a picture of one in flight. The tail looks like the rear of a late-'50s Cadillac. --- David K. Cornutt, Residentially Engineered, Huntsville, AL email: firstname.lastname@example.org I'm a rocket scientist.
