When I am on final approach just prior to landing (I’m a new pilot, about 100 hours) my eyes are scanning three things. Air speed, VASI or PAPI lights, and runway centering. When those are correct the landing goes well.
One thought. When doing a go around and applying full throttle with the full flaps extended, the nose will pitch up and require considerable forward force on the yoke to prevent a stall. Sounds like that is what happened, the nose pitched up and the tail hit the ground.
In a piston engine propeller airplane, full power is almost inmediate. In a turbine engine, especially a turbo jet, you need to allow for turbine spool up, which takes a precious few seconds. These guys applied full power less than two seconds before impact. Way too late. Again, IMHO.
Also, as far as visual cues, one more thing you need to do is to look at the far end of the runway to judge your sink rate.
It should be noted that the act of landing involves the decrease of speed and a stall at the precise moment before the wheels are touching down. The object is to quit flying.
It would seem to me the error was in not aiming further down the runway. Rather than landing on the numbers, he could have extended his point a little for a first attempt in that aircraft. The runway is long to allow for that specific event
