Original photo caption: "The 'Sentinel', popularly called the 'Flying Jeep', built by the Stinson Division (Wayne, Michigan, USA) of Consolidated Vultee Aircraft Corporation.
This small, rugged, highly maneuverable new plan is designed to be the 'eyes upstairs' of the artillery, tank corps, and infantry. Carrying a pilot and an observer and packed with radio equipment for communication with all types of ground units as well as other planes, it can hover and maintain altitude at an exceptionally low speed while directing artillery fire or the movments of tanks or troops below.
Like the auto jeep, this Flying Jeep is designed to cover almost any kind of terrain, to go wherever the ground troops go. It can get in and out of a cow pasture, or plunk itself down on a highway.
The 'Sentinel' is powered with a 190 horsepower horixontally opposed Lycoming engine. Wing span is 34 ft (10.36 m); length 24 ft (7.32 m); weight 2,100 lb (953 kg)."
