Flight TWA 800 in the past 10 years, Egyptian Air 990, Alaska Aviation 461, and many other flights have one thing in common. All three are private airline flights, no survivors. All of these occurred over the past five years. Due to the large number of deaths on each flight, all three accidents were widely announced within weeks after the accident. At TWA 800, all 212 passengers died. Flight 461 in Alaska State, all 167 people died on Air Egypt 990 flight and all 88 people died at the last flight. From the explosion of fuel tanks to the possibility of pilot suicide, the causes of these and numerous other accidents, many collisions remain unknown

Of the 70 TWA flights, only three wills were identified and the rest was buried in the land in Flagstaff 's cemetery in Arizona. On United flights, 29 people can be identified. For the other 29 people, their body only needs 4 coffins. A report took 10 months to compile sketched the crash site. United Douglas DC-7 began to succeed at a slightly faster rate of 340 mph and 304 mph at the super constellation. As their sight was blocked by the weather, the report said that each aircraft had gone out of the cloud at the same time, and the United Air pilot was too late to avoid the collision, but that risk can be seen first I insisted. United 718, diving and turn left on the plane, the left wing hits the TWA 2 tail and the rear torso and cuts the aft part of the aircraft

I made a disappointing start on this day. Because of the half hour delay, TWA 2 flight departs from Los Angeles at 9:01 am and goes to Kansas City. Just three minutes late, United 718 took off from the apron and started a journey to Chicago. The flight of the latter fly to the destination in the north, but its route starts from the south side of TWA 2. This means that their flight paths are designed to cross almost certainly at different times, despite different heights. However, the morning of June 30 is cloudy. When TWA 2 encountered bondage in California and Arizona, Captain Jack Gundey asked the Air Traffic Control Division to allow the flight to fly 2,000 feet above his flight. Knowing that co-flight is expected to pass through this area, the airline refused his request. But later, when Gandhi demanded "1000 at the top", it meant that it was 1000 feet above bad weather, his request was approved.
