Rick Hendrick, owner of Nascar team Hendrick Motorsports, his wife, and the two crewmembers suffered minor injures when their Gulfstream G150 overran the runway while landing last night at Key West (Fla.) International Airport. The jet, N480JJ, is registered to Jimmie Johnson, who drives for Hendrick Motorsports. Unconfirmed media reports indicate that the aircraft brakes failed on landing.
