Ele vai tentar um pouso forçado, mais é uma manobra arriscada.
He is going to try an emergency landing/forced landing it´s a risky manoeuvre.
(a forced landing is a type of emergency landing, see Wikipedia for more about this subject.)
Usually the pilots, I think, would say that at most it´s a serious situation (to be handled). They are trained to perform it, so wouldn´t be a risky manoeuvre to them. At least it´s the first assumption.
As for jumping over 50 cars or driving backwards at high speed, that would be a dangerous stunt indeed. If you are not a pro stunt performer, one of those that performs in movies, I mean.
Or even to them it is dangerous, just that they take controlled risks!
