In 1938 the pilot of a BOAC plane en route to Iraq, flying in dense cloud and rain at 8500 feet, reported that a ball of fire had entered the rear cabin and burst with a loud explosion. One or two minutes later it (or another lightning ball) entered the cockpit through the window which was open for visibility, singed the hair and eyebrows of the pilot, then bounced on through the forward passenger cabin and into the rear cabin, where it again exploded[IX-12]. Similar incidents have been reported by Soviet pilots. In the summer of 1956, a Soviet transport plane flying at about 10,000 feet was struck by ball lightning during a very rough flight through a stormy cold front. A fiery red-orange ball ten to fifteen inches in diameter appeared in front of the aircraft, swerved to the left, struck the left propeller and exploded with a loud detonation and a blinding white flash. The intense electrical discharge destroyed radio communication between the plane and the ground and disabled the radio compass. In attempting to disconnect the antenna, the radio operator received an electric shock. When the plane landed and was examined, one of the blades of the left propeller was found to be slightly damaged and a small fused area and a deposit of soot were found on the edge of the airfoil a few inches from its end[IX-13]. A similar case occurred in December 1956, when a Soviet jet had entered a storm cloud and was climbing through it. As the plane reached the top of the cloud, at an altitude of 12,000 to 15,000 feet, ball lightning suddenly appeared a short distance ahead and to the right of the plane, and exploded with a dull but piercing noise and a blinding flash; the ball then broke into a series of beads. Although one of the engines close to the ball died at the instant of the explosion, the crew were able to start it again and the flight continued normally. After landing and finding no mechanical damage, they concluded that the engine had failed temporarily because the explosion had formed a region of intense rarefied air that deprived the engine of oxygen[IX-13]. Ball lightning has often been reported near the ground, as in the Levelland case. In the summer of 1934 Mr. Durward, a British meteorologist, while driving along the bank of a lake observed the phenomenon: “It began to rain heavily, with slight or moderate thunder and lightning. His son, a boy of twelve, was opening the iron gates, spaced at intervals on this road, and found one difficult to open. Mr. Durward, while walking the short distance from the motor-car to the gate to assist his son, saw among the pine trees on his left what looked like a ball of fire about 12 in. in diameter moving towards them. It struck the iron gatepost farthest from the latch. There was no noise, but the boy, who had his hand on the latch, gave a yell; for the next few hours he was unable to lower his arm.”[IX-12]
