TRIAL WYVERN: CONTAMINATION PICK-UP ON HELICOPTER OPERATIONS OVER CONTAMINATED GROUND (title on label) [Allocated Title]

Series of contamination tests on Wessex and Puma helicopters.

Detector pads are attached to the fuselage of a Wessex helicopter while a lorry (and later a tractor with crop-spraying equipment) sprays "chemical agent" over an airfield (possibly RAF Odiham). Square detector pads are also laid on the ground. Helicopter flies over and lands on the "contaminated area". Later, the pads are removed and aircraft hull is tested for contamination using ultraviolet light before decontamination (of both helicopter and airfield). Brief shots of Puma helicopter flying through a plume of black smoke.
