The Constellation had strayed off course because of an incorrect radio compass indication due to the effects of thunderstorm activity in the area. Believing to be over the Skopje beacon, the crew changed the heading to 142 degrees. At 40 miles east off airways Amber 10, the aircraft entered Bulgarian airspace and was intercepted by the Bulgarian fighters.
PROBABLE CAUSE: "The aircraft sustained a hit or hits which caused loss of pressurization and a fire in the heater compartment. The aircraft broke up in mid-air due to explosion caused by bullets hitting the right wing and probably the left wing together with a projectile or projectiles of large calibre in the rear end of the fuselage."
