Good point Mr F.
Are the Pegasus engines particularley unreliable or are you just being hypothetically cautious.
Perhaps an engine developed from the Pegasus, bigger fan etc capable of providing enough thrust to allow an engine-out in the hover mode would do the job.
I know it all adds up to more weight and then we get into the thrust/weight paradox all over again.
Just thinking out loud of course but i'd pay to see something the size of a 146 go over a ski jump!
