Pictured here is Princess Diana being removed from an SAS kill house after conducting a live fire training exercise.
The mock hostage rescue was to prepare her and her husband Charles in case they were ever to be kidnapped by terrorists and how to act when the SAS would storm in to save them.
A flash-bang grenade was thrown in and, without taking a breath, 4 SAS soldiers dispatched the targets in a hail of bullets. Diana covered her ears as bullets whistled around, while Charles recoiled in shock at the noise and action.
The exercise went off without a hitch besides when a flashbang accidentally burned Diana's hair.
Before taking part in the rescue, Charles signed a humorous typed letter which still hangs at the SAS HQ.
It reads: “Should this demonstration go wrong I, the undersigned Prince of Wales, will not commit B Squadron 22 Special Air Service Regiment to the Tower of London. Charles.” #whodareswins #stayzero #zerofoxtrot
