FB,
Yes they can. But by looking at the pics, both nacelles were broken and altering incidence angles of the turbines on both sides. I've seen guys fly Mibo's on one engine fine without too much yaw issue. I was there...Mike was brilliant at getting this bird down in one piece. I too saw right at 3 min into the maiden, on straight and level flight, it had an abrupt change in pitch...very severe. His approach to landing was very pitch sensitive the whole way in. It was a great save for sure on Mike's part. BV and Dustin were "Johnny on the spot" to get firsthand intel to get a fix going for this bird.
