Also the military were driving the Nomads through manouvres that were obviously a lot more stressful on the airframe than the civvies would have done to them. I have been in the back of one of the Tindal beasties when we did a few wing over type manouvres and hugging the earth to stay away from the fighters. All good fun but pretty hard on the plane. I'm sure the ARMY nomads would have copped similar or more.
