A Southwest flight from Las Vegas to Hollywood Burbank Airport was halted at the last minute due to a lack of clarity on the runway. The pilot informed passengers that the ordered runway was not clear and that they had to abort the landing. The plane's wheels briefly touched the ground before taking off at a steep incline. The incident occurred the same day that the Federal Aviation Administration announced an investigation into a close encounter with a military Blackhawk helicopter that crossed into the flight path at John Wayne Airport.
