Though I will grant you that they would reveal the rather embarrassing problem of not being able to actually start the engine before reaching the runway :) | |

I don't think the results of the simulation were actually published anywhere, but I've seen them in person and they indicated that, for the assumptions under investigation, this would have been an NPV-positive initiative. Can't rightly say whether this is something that would have also turned out positive for taxi-outs and -ins as supertugs are quite fuel-hungry and expensive in their own right, but the approach may be a viable third option, at least at major airports. | |

To me, though, it seems like maybe taxiing out under power isn't such a bad idea, since it seems like you'd be more likely to detect any potential problems with the engines before takeoff that way. | |
