The pilot apparently landed, got a wheel off the paving onto soft (softer at least) ground and then elected to add power. None of our engines are probably powerful enough to overcome the drag of a wheel on soft ground, but I would certainly think that the drag of a locked wheel on paving is enough to overcome most any yaw moment due to the soft ground. The lesson I can think of is that this is one time where fast reflexes and decisive action counts. A really hard application of differential braking would possibly save the day. Application of power might only increase the speed of the crash. Go- rounds after the plane is on the ground don't generally seem to be a good idea. but what caused the tumbling? A collapsed nose gear combined with a tall, short wheelbase gear layout? If the nose gear collapsed the canard would increase the downforce on the nose, while the tail of a conventional plane would decrease it.
