Ahhhhhhh - Shacklebombers.....
Went for a trip in a Mark 3 Phase 3 from HMP Kinloss in 1969. We bounced a Noggie trawler at about 250ft in the cold, black, wet night; poor bug.ger was rolling from gunwale to gunwale! Could still hear the engines 2 days later. No H&S in those days....
Got a trip back from Lossie to Leuchars 12 years later in an AEW. Dreadful thing - it would have been quicker to have walked... But amusing as it went boing......boing.....boing all the way down the runway.
But they were useful in filling gaps in the radar horizon. Was Bear-chasing once in the '10 when a Shack picked up the contact way on the beam. We scuttled over to intercept it and nabbed the Tovarichi on their way home. Got some good piccies as well!
I once was asked by a Signaller in a Shack to relay an Ops Normal back to Fishfleet HQ - "Position this, estimate that, ETA Lossie....etc etc" We read it back and added "Was that ETA...today?"
