The Twotter is a magnificently rugged little aircraft - loved every minute of the 1500 hours I spent on it, and have to say that technical problems were really rare. There were several occasions (not technical related) sitting in the left seat of a 777 in the middle of the night staring into the dark somewhere over an ocean with 10 hours to go that I would have willingly gone back to a Twotter if someone would have paid me the same money
. Having said that, the Boeing is a bloody fine piece of kit, too.
