PanAfrica: Across the Sahara in 1941 with Pan Am, by Tom Culbert and Andy Dawson (1998)

 

Now in its fourth printing, this excellent book tells a war story that few know about: At a time when the success of the Allied war effort hung by a thread, Pan Am built airfields and instituted a vital intercontinental airlift across some of the planet's most inhospitable and dangerous terrain, across routes stretching almost around the globe.
