Yup the pilot went on exchange and the navigator took much of the blame because it was a 2-stick aircraft and thus had undercarriage indicators in the back!
The pilot bit is true... the nav bit a little unfair. He was after all a student.
I remember that incident well because the Saturday morning after I was dragged in front of the BOI because it was deemed I had trained the caravan controller - (who froze)
The BOI to be fair were very good and the chap knew darn well he was speaking to someone whose only crime was to bother to fill out how many times in the log he had fired a red very when the person concerned was training.
I never did (and never will) forgive the SATCO concerned, but it did teach me that men in green suits are a breed apart, ask the green suits I worked for after that incident.
