They didn't call the F-117 the 'Wobblin' Goblin' for nothing. If the fly-by-wire failed you pretty much had to eject as it was virtually uncontrollable with the amount of vortices generated. As an aside though, one of the test aircraft lost one of the V-tail vertical stabilisers and the fly-by-wire did such a good job, he didn't even know it was gone until the chase pilot told him to put it on the ground pronto!
