THE AIRPLANES WERE FLYING ABREAST ONE ANOTHER AND THE PILOT REPORTED THAT HE WAS WATCHING THE OTHERS ON EITHER SIDE OF HIM AS FORWARD VISIBILITY WAS NEAR NONEXISTANT DUE TO THE AIRPLANES CONFIGURATION. THE TERRAIN WAS ROLLING AND RISING IN FRONT OF THE FLIGHT. THE PILOT THEN HEARD A LOUD BANG AND THE AIRPLANE HAD A TENDENCY TO ROLL TO THE LEFT WHICH THE PILOT WAS ABLE TO COMPENSATE FOR.
