Re the climb out performance of the Argonaut, here is a passage from ex-BOAC/BA Captain, Peter Duffy's book, "Comets and Concordes (and those I flew before):" heading is "Argonaut departures;" "The departure from Rio was usually on the direct route north to Recife, and not via the harbour entrance. This saved conflict with air traffic at the city airport, and also mileage, but involved flight up a valley over rising ground to the town of Petropolis. The ground rose to match the climb rate of a fully loaded Argonaut, and it seemed as if we were flying up the main street of this town to just clear a large church.........I do not remember many dreams, but have a recurrent vision of this departure, with hills on both sides of the a/c, and involving weaving to avoid roof tops" (!)
