Pan American Airways: Missions of Mercy and Evacuation Flights by Charles Imriani PhD (2020)
From almost the start of its sixty-four years of operation Pan Am was called upon to evacuate victims of war, revolution, acts of terrorism, oppressive regimes, and natural disasters. The airline and its people were always there when called on; there was never a shortage of volunteers. These volunteers were real heroes, and this is their story. You won't find this story in most history books, but you'll find it all here, in Pan Am's Missions of Mercy and Evacuation Flights.
