Captain Dan Mossman sings to his passengers in the wake of 9/11. Captain said:"After 911 I did that for my passengers (either in the boarding area or on the aircraft before leaving the gate) for about 3 months. I had been carrying a Martin Backpacker guitar with me for years and after 911 I was inspired to do that song for my passengers. I have always greeted them personally and this just naturally evolved"...
