Just a quick question. How much damage would hitting a hole have done? How much of the aircraft's weight would be on the mains when it crossed the hole? The wheel would have spent about a tenth of a second unsupported; how much could the oleo mechanism have extended it during that time? Add to that the very small amount that the aircraft would have descended over the 10ft (Looks like) diameter of the hole. The same hole would have been a far more serious hazard later in the landing run.
After this excellent landing you could have used the airplane again!
