Boeing 707

Following an uneventful transatlantic flight from New York, the crew started the approach to runway 20 at Brussels-Zaventem Airport. On short final, while at an altitude of 900 feet, the crew raised the landing gear, increased engine power and made a go around. The plane made three 360° turns to the left and climbed to 1,500 feet. During these turns the bank angle increased more and more until the aircraft was in a near vertical bank. The wings then leveled, followed by an abrupt pitch up. The 707 lost speed, started to spiral rapidly towards the ground nose down, crashed and caught fire. All 72 occupants were killed as well as one farmer working in the field. Among the passengers were 17 members of the US National Hockey Team who were flying to Prague to take part to the World Championship.

The four engine aircraft departed Idlewild Airport at 1157LT with a crew of six and climbed along the shore of Long Island on a training mission. 23 minutes later, the airplane christened 'Flagship Oklahoma' banked left, entered a dive and eventually crashed into the ocean five miles off shore. Few debris were found off Montauk Point and all six crew members have been killed.

A Boeing Airplane Company test pilot was acting as an instructor-pilot on a demonstration and acceptance flight prior to the aircraft being delivered to the customer. The company was also utilizing this flight time for flight instruction purposes in qualifying airline personnel in the aircraft. The instructor-pilot demonstrated several maneuvers, including Dutch Rolls, to a pilot-trainee, an airline captain who was making his first training flight training flight prior to checkout on the Boeing 707. The instructor-pilot initiated a Dutch Roll in which the roll-park angle of the aircraft reached 40 to 60 degrees. This bank angle is in excess of limitation set by the company for demonstration of his maneuver. The pilot-trainee, who was to make the recovery, rolled full right aileron control while the right rank was still increasing. The instructor-pilot immediately rolled in full opposite aileron. The airplane stopped its right roll at a point well past a vertical bank and then rolled to the left even more violently. Several gyrations followed and after control of the aircraft was regained, it was determined that three of the four engines had separated from the aircraft and it was on fire. The fire rapidly reduced controllability of the aircraft and an emergency landing was attempted, however, the aircraft struck trees and crashed short of the intended landing area because power on the engine remaining had to be shut down to keep the aircraft wings level. The aircraft was destroyed and four crew members were killed while four others were injured.

The crew was completing a local training flight at Calverton-Peconic River Airport, Long Island, New York. While approaching runway 23 at an altitude of 1,000 feet, the airplane yawed to the right, stalled and crashed in a field located three miles from the airport. The airplane disintegrated on impact and all five crew members were killed.
