I must confess I had to call a friend ( who knows just about everything aviation) to confirm it but recall reading somewhere years ago about the amount of deception that Co's did to hide or give the wrong impression to competitors or the enemy
The Japs flooded the Pacific with confusing messages prior to Dec7 1941. Deception is alive in every field of endeavour from the grubby politicians to little kids playing at kinda!Enemy deception is a complete field in itself, in the military. There are large teams involved in enemy deception.
During WW2, they built dummy airfields complete with buildings, built thousands of tanks and truck dummies, and even produced dummy large scale troop movements, complete with washing on the lines! They even set up dummy harbours!
The U.S. started their "Ghost Army", an Engineer group, modelled on the British enemy deception effort in the Middle East, called Operation Bertram.
Where the British used dummy tanks and vehicles built from plywood, the U.S. used inflatables for tanks!
The Americans indulged in electronic and signal deception on a huge scale, and even had huge sound systems broadcasting military movement noises!
During WWII, the 23rd Headquarters Special Troops, or Ghost Army, used sound effects, disguises and inflatable tanks to trick German troops. Now, a Lexington filmmaker is working to make their story mainstream.www.wbur.org
