An Air National Guard Lockheed T-33 aircraft (35966) took off from Martin Airport at 11:07 for a VFR proficiency flight. Just before the collision the aircraft were observed in the area west of Brunswick flying parallel easterly courses with the T-33 some distance behind and to the left of the Viscount. The T-33 quickly overtook the Viscount and made a gentle right turn during which it struck the forward left side of the fuselage of the Viscount at 8000 feet. Both aircraft crashed, but one of the T-33 crewmembers ejected safely.
At the time of the collision the Viscount flew at an airspeed of 235 knots and the T-33 at 290kts; giving a rate of closure of 195kts.
PROBABLE CAUSE: "The failure of the T-33 pilot to exercise a proper and adequate vigilance to see and avoid other traffic."
