It might be one of those situations where while technically possible, the benefit may not be there given the fact that the thrust ratios are way different between the two types of plane, and the importance of the control surfaces differs significantly as a result. | |

Things like a volcano erupting, a space shuttle launch. Rarely something that can't be corrected for, but if the normal controls are dead... I'd guess if done deliberately it might be used as a control system, but it'd be hard to control. | |

That means it's harder to turn as the torque arm is a lot shorter. The F15 also predates thrust vectoring, so it's similar to commercial planes in that respect as well. But yes, you do need two wings - that's not waht this question was about. A wing usually isn't considered as a flight control surface. | |

| Apr 1, 2015 at 15:21 | comment | added | Calphool | It's also debatable whether such a system could be implemented a typical airline transport jet. Military jets practically fly on thrust alone (theaviationist.com/2014/09/15/f-15-lands-with-one-wing). Airliners still depend very much on their wings, ailerons, elevators, and rudder for stability. Although UAL232 provides some anecdotal evidence that it might be possible, a lot would depend on the nature of the situation causing the emergency. | |
