The terminology used by 214 Sq had pretty well settled down when I joined as a co in 1961. There were still aircraft lined up for a first go. In my time there was a Scimitar that tried and failed, because the probe nozzle was too close to the aircraft nose to fit inside the drogue, A very awkward Argosy trial owing to the speed differential.Then there was a Sea Vixen that not only took fuel from the Valiant but passed some back from its own Mk20 pod. We also had Trial 448 which is possibly still classified but was a very busy time for us.
