It is difficult to believe (impossible frankly) Roush would not have familiarized himself with the landing protocol for such a heavily attended event. Especially in view of his history of air craft business ventures.

This assumption, is based on the premise that he MUST not have known because he did not follow procedure by doing a "go round". It ignores the possibilities that a go round, early or late, could NOT have been done as easily as has been suggested. There seems to be an issue of endangering himself or other air craft if a go round was attemped. This does not suggest he was unfamiliar with the procedure, but was unable to follow it. Because he got "behind"? Speculation at best, but if so, it warrants further speculation about WHY/HOW he got behind? That could have started with the "obvious" confusion in the control tower when THEY "got behind".
