So here's another one,

Take said Xterra and strap it to a dyno.

Take a Rocket of sufficient size to propel the X without the engine and strap it to the roof.

Operate the engine to gain let's say 90MPH or near the limiter, Perfectly safe on the dyno right. Disconnect the straps and fire the rocket.

Select those that apply:
A) Will the rocket propel the X off the Dyno? (Plane will fly crowd)
B) Will the X remain stationary on the Dyno at the same 90MPH? (Plane won't fly crowd)
