On a South African forum it was reported that they had planned to use water/meth for this take off. Apparently this was infamous for causing backfiring leading to the auto feather engaging so many crew didn't arm the auto feather. The use of water/meth could well explain the popping we hear on take off. They also had a habit of exhaust system fires aft of the engine.

Looking at the vid from the Cessna I would guess that they had both engines running until they turned onto base considering the speed they were doing. Something happened on the base leg for them not to turn onto final. May be they shut down the engine and it wouldn't feather.
