Re: Delta Private Jets...aborts takeoff...catches fire....

Looks like one thrust reverser is still active after the overrun while the other is stowed. I don't know a ton about the Cessna Citation series so I am not sure how it would be to counter it but having asymmetrical reverse thrust would not be a fun time on a lot of airplanes. Depending on damages, ...
