... have to disagree. Our aircraft was already occupying the runway and had turned around to commence takeoff. It wasn't a case of a student taking longer to do checks etc, it was just poor airmanship on the part of an impatient Pitts driver. The other aircraft holding behind it didn't seem to have a problem with waiting their turn.... And our aircraft actually has a better takeoff and climb performance than a Pitts, so not sure that would be relevant mitigation either. Sadly, it's just cr@p airmanship.
