George, that is almost like making a schedule with a fleet of C-54's. In the old days the C-54 in operation with Greenlandair (partly owned by SAS) were said to be the most reliable three-engined plane around! Another story goes; on the PA; this is your captain, we have just lost an engine, so we expect to have a ½ hour longer flying time to our destination. A bit later another spluttering engine had to be shut down and again a slightly longer flight was announced. So, a bit later yet another and another delay announced when a passenger was heard mumbling "great, now if we loose the last engine we have to stay up here for ages. . . "
Hope your letter arrives swift and safe. I shall have my boarding pass ready for this flight @gblair!
