Yes, I’m sure it is possible; I did some quick calculations after I’d posted based on the, often quoted, distance to the Falklands of 8000 (statute) miles that worked out at 18.5 mph so it sounded about right.

Talking of the distance to the Falklands I remember a story being told on TV where (I think) First Sea Lord (Sir) Henry Leach told Prime Minister Thatcher that it would take the Task Force three weeks to even reach the Falklands; Thatcher replied ‘you mean three days’, no replied Leach ‘three weeks!’ Still, I think Thatcher had a better grasp of military matters than any Prime Minister since! :rolleyes:
