Here is a tinted postcard of the Link Trainer Building at Napier Field, Dothan, Alabama. Napier Field was built as a military base during World War II. The postcard description is ‘ “Learning to fly by not flying” these Cadets and their Instructors are busily engaged in piloting Link Trainers to a successful landing by the use of instruments only.’ It was published by Dothan Cigar & Candy Company.
Notice the light horizontal streaks on the floor? Likely a photo touch-up covering the large cables between the trainer and the instructor’s console.
