I'm guessing that this is not a spur of the moment question...?
My initial thought would be that as long as 1) your removal of the door was iaw the flt manual (and company procedures) and you were authorised to carry out the removal. 2) all aspects of the Flt manual were complied with as regards floor loading, COG etc and that the flt manual did not prohibit cargo sticking out of the aircraft 3) the load was adequately secured, then i can't see how you would be guilty of reckless endangerment.
who thinks you were?
