Well, if Air Florida Flight 90 would be pushed like this instead of using reverse thrust maybe it wouldn't end in Potomac. Although it is unthinkable on an airport like DCA regardless if such solution would work the best for given circumstances.
I live in ex-soviet block country (EU now) and I am more and more horrified by the amount of regulations implemented on anything.
This kills "can-do" attitude in many instances.
Can't comment on regulations in aviation but I can imagine that being stuck like this in remote siberian airfield and wait for conservative way to solve the problem would probably mean to stay there for days.
We have also different attitude to (mis-)use the legal system and I can hardly think that anyone involved would sue the carrier after such a situation. You would merrily explain your experience to your friends but you wouldn't ask your attorney to act.
