This accident bears comparison with the B-17 where the crew put the gear down,and then failed to use the other cross runway.In this case with only one hydraulic pump,it would take longer for the gear to come down evenly and lock,leading to a possible collapse on landing,loss of control,etc,and the extra drag as well..Same with the flaps...If crashing is inevitable,fly it under control as long as you can,never give up...
Brilliant bit of airmanship by the crew.....!
