Engine failures of this sort were by no means unknown on such flights in those times, and a delay of one or more days to get things fixed was just one of those things, so little long-term recording of such. Engine failures, alias "catching fire", which probably sounds more spectacular than it actually was, were a periodic event for all operators, large and small, doing such work. The Britannia took several years to cure engine problems, which never caused actual harm to a passenger flight, but were better than the Wright R-3350 powerplants fitted to Constellations/DC7s which had preceded them !
