Most common question I got when I flew: "What do you do if the engine stops?" My answer: "Turn around go home and land" It does help that I started out on gliders (sailplanes) first, of course... but losing the engine really isn't that big a deal in level flight in many small aircraft (or even big ones actually - a 747 has a surprisingly decent glide ratio (not actually surprising if you think about it, tbh)). I've never flown twin engine, but as others have mentioned, losing one engine in a twin can be catastrophic - unless it's the Boomerang of course ;) http://en.wikipedia.org/wiki/Rutan_Boomerang http://en.wikipedia.org/wiki/Rutan_Boomerang In summary: I would choose zero engines, one engine, or four engines - but not two.
