Lockdown idleness has led me to a daily, rather than, mostly, week-end sweep through threads and discovered this one today. Deep joy. Scrolling down, I wondered why there was no reference to .Morton Air Services who operated both the Dove & the Heron, but, there it was.
I was a wanabee at the time & employed as a D/O at Gatters. Apart from Tommy Gun, Charlie Moss was Crewing Manager but an Ex Radio Operator . I was ordered to ready the Dove as Tom & Charles were going to get airborne for some Air Test, or something. All ready, in swept Tommy asking for the "Operations stop-watch followed by Charles carrying a headset. Blimey, off they walked from the Flight Watch Office direct to the Dove, parked outside (I ordered that ) and off they went. I wondered if we would ever see them again . Halcyon days.
