Tom Cruise is famous for completeing all of his own stunts in the films that he is in. When helicpoters are involved you can't expect him to sit back and let someone else do the work.
This skill level is impressive! The fact that Tom Cruise was able to complete 2,000 hours of training, and pull off stunts on this level ALL while acting at the same time is amazing.
I am DEFINITELY going to see Mission Impossible-Fallout. Why isn't this my life? I would definitely have 2,000 hours under my belt if I had my own helicopter. SOOO JEALOUS!
