June 1967 changed all that when two UK-registered charter aircraft crashed at Stockport and Perpignan within 24 hours of eachother.
Due to press comment, the old aircraft were quickly replaced by jets such as One-Elevens, 737s and Comets.
The above is incorrect. Dan-Air started using Comets in 1966 and Laker had ordered it's 111s before the accidents.
