I did a 3 engine ferry on a DC 6 firebomber once after an inflight shut down due to a spun blower seal. The seal failed right at lift off from a shortish dirt strip of course.
.
The engineer had a 3 engine prep checklist and the company applied for a ferry permit. Takeoff procedure was full wet power on the 2 symmetrical engines holding the brakes and them feed in the remaining engine as the airplane accelerated and the rudder became effective. In practice not a big deal and we had the benefit of a cross wind from the "right" direction.
Company had a fully built up QEC with prop and tin on always ready to go . We rolled up to the company hangar at 0800 and they had the new engine hung by 11:00 It took longer to do the paper work and runup checks than it did to re and re the engine. We took off for our base fully serviceable at 16:00. It was fun to watch the guys at work.
