At Ballykelly, we had three John Wood's on our crew on the Shackleton Mk2.
( I was so junior and I thought my world had come crashing down when I saw the inside of a Shackleton and then I didn't quite understand why 204 sqn put all these Woods on the same crew - but that was explained to me later)
One was a F.Sgt Navigator, one a comissioned AEO, and one a F/Sgt AEop or maybe he was a F/Sgt Signaller.
Although the first John Wood was the junior of the Navigators, the comissioned Nav was often prone to air sickness and vomiting so the N.C.O. nav seemed to take the majority of the responsibility for navigating by jumping around in each of the Nav's seats whenever it was deemed necessary, like Stage 2.
The day I handed back my immersion suit and helmet and drove away from BK and on to Larne and Stranraer and then then down to St. Mawgan for the Nimrod O.C.U. I breathed a huge sigh of relief. But that is another story which involved Headley Court.
This was all circa 1970 with Fg. Off Hunter as the skipper.
