DARN... So sad to see.
I worked for this company for a year as a crew scheduler in the Operations department, when I was attending University.
Its generally a cargo company now, and its owner Mr. Conny Kalitta is a big Nascar Race Fan, and I believe he also had a stint in Race car career, when he was young.
The company also used to have Hajj Operations, carrying pilgrims to Holy Mecca, on chartered basis. When I was there the company was called AIA (American International Airways), and was in process of switching its name to Kalitta Air.
The Movie AirForce-1 used the Boeing 747 that belonged to AIA (now Kalitta Air). The Hollywood crew came over to town of Oscoda Michigan and shot some scenes.
