Not one mishap occurred during all the landings 4-6,000 of them.
Someone suggested writing new rules/regulations/directions in case it ever had to be done again.
Some one said "how could it have been done any better" and it was decided that the lack of rules allowed everyone involved to make on the spot decisions about what was best to do and writing news rules/instruction, etc would only hinder that freedom.
No new rules were written. I thought God, common sense won out.
Yes, it's called "Grounded on 9/11" and ran on the History Channel..
