My dear chap (Arizona Airline Captain), it's not a case as you suggest of a fixation with 'mayday'.
Were you there or heard it? No, but must have the two pennies worth, just in case.
How did you arrive to the conclusion it was a transport aircraft? God only knows and frankly who cares.
But hey, what do I 'wound up like a cheap watch' pilot know about it.
Well, I heard some of it and the poor guy putting the mayday, just kept calling mayday and it sounded 'a little' concerned. We thought at the time.... poor bugg*er….put yourself on his or their situation. But of course big airline captains don’t worry about things like that, at least those that fly a real mahogany desk airliner.
Anyway, I just hope there was a safe outcome.
