Ah, the infamous harmonica playing captain, yet another sighting (listening)...
I first heard him many years ago when he was on the "9s" out of MDW-MSP.
I heard he was "upgraded" to A319/A320 doing california flights.
Did he do the train whistle, its time to leave?
One of the deviating from the scripts from the FAs on NW I heard was after the double bells before landing said "Badda Boom, Badda Bing, Ladies and Gentlemen there is the double ding we are about to land"...
