Changing hands
Once, when crewing the old DH Heron Hobart to King Island, the company's big cheese was in a sister aircraft going into Flinders Island. (The geography is not relevant to the point, but to me it fixes time and place - so stiff!)
Big cheese has his usual bout of verbal diahorrea and can't shut up talking to the one or two possibly conflicting others in his vicinity . . . . on and on and on he goes . . . finally unkeying mike and instantly is met with the sardonic tones of our chief pilot (one Nigel Peart) - "Change hands Dallas, change hands."
