#13-The 707-420 was powered by Rolls-Royce engines. The type was operated by BOAC (BA) Air India, South African Airways, Qantas, and I believe Cathay Pacific.
In 1974, I took a Conway powered BA 707 r/t YUL/PIK/YUL as part of a student trip to Scotland. At Prestwick on the return trip was a VC10 next to us going to JFK (or BOS).
