Romber should have at least stopped to see if everyone was OK from the wreck in Africa, I agree. There were also another couple of times (telling the bus driver not to open the back set of doors) where their character was tarnished. Although they played the game well and came up with some very smooth/smart moves, their character determined their ultimate fate in the race.
So it was their character that persuaded the pilot to let team Juchenna on the plane?
