Roswell Report: Case Closed 

Fig.20. Balloon Branch Communications Technician, A2C Ole Jorgeson, now a retired Master Sergeant, in the rear compartment of an M-43 ambulance, Ambulances of this type were converted by the Balloon branch to communications vehicles in the late 1950's. It appears the witness described the two panels painted Air Fore blue (lower right and left of ambulance) as "bluish purplish" "wreckage" that looked kinda like the bottom of a canoe"  and the stenciled writing above them as "hieroglyphics" see figs.21 and 22 on the net page.
