Weather could have played a role in the flight path of the Malaysia Airlines plane that crashed in Ukraine.
Storms in the region may have sent MH17 on a route further to the north.
Thursday's flight path was about 200 miles to the northeast of the most recent path frequented this week.
The route was also further away from the region restricted by the FAA for U.S. air carriers.
Watch video above to see the impacts the route change may have had on Thursday's deadly crash.
