*Dons non-pilot flame retardant gear*........
Original post says "FAA noted some irregularities in radio transmission...." then goes on to imply that they had a guy on the ground quick enough to 'interview' the pilot concerned.
Two questions...(a) Am I incorrect in thinking the 'interview' in the lounge took place when the a/c landed?... if it was at a later date surely it would have been scheduled in an office, and (b) Does the FAA 'monitor' radio traffic in real time?
