n5296s - it could be survivable from a low hover or a situation where you are so close to the ground that an immediate landing could be made (probably still roll over though).
In the high speed cruise it might not be so dramatic until you slow down so perhaps a very high speed running landing might be possible, drooping the Nr to reduce the TR power (again you are probably going to roll over)
Other than those two extremes I don't believe there is any solution - they were extremely unlucky.
