Here we have one of those fantastic panoramic photos that was widely popular back in the day. Taking such a shot was not in the realm of most photographers and so one had to call on the experts: the National Photo & News Service of San Antonio, Texas. It was one of their photographers (E. L. Rothwell) that made the journey to Selfridge Field, Michigan in the summer of ’37. His tool of choice was a “Cirkut” camera, a truly ingenious device that, while pivoting on a level axis, exposed a roll of film which advanced in synchronised movement to the horizontal action of the camera. Capturing for posterity the 1st Pursuit Group required five feet of film (the photo measures 5 feet x 10 inches).
As stated, the photo was taken in 1937. Summer time, if one takes in to account the many open windows and the fully-leafed trees (and, according to the clock on the operations building, it was 9:10 AM). The squadrons are the 17th, 27th, and 94th Pursuit, the aircraft, of course, is the P-26.
Most of these buildings seen 84 years ago are still in use today.
