Boeing 747-100(3)

Last time, we talked about the engines issue of Boeing 747. Although the team immediately work on the engines after the exhibition, there is still a big problem. No company can provide the engine that can left even half of the weight of Boeing 747. Pratt & Whitney Group got one engine just right for lifting the plane. But it is still in test process. It is the JT9D.



This turbo fan provide low noise and amazing push by it brand new design.



But it seems they hope too much. In the test, the engine was shaking and the "Bang" sounded. No one knows where is the problem. 16 engines were destroyed. Boeing couldn't wait anymore, they need to prove to the world. In February 9th, 1969, test pilot Jack Walldell get on the test plane. At 11:00 AM, RA-001 drive to the runway.



It was the moment of truth, Jack pulled up the nose. All went well before Jack collect the flaps, there was a strange sound.





But every things went well and the plane landed.



Boeing now need to prove that the plane is safety enough to carry passengers.
The test were beautiful.


But engines problems come again. Boeing thinks it is time to let Pratt & Whitney Group worry about that. They asked the president of Pratt & Whitney Group to the 747 and flew. Jack shows the issue and the president were extremely afraid after two engine Bang. He said:" I got it. Fine." The reason of flame was found.
After the first plight from Panam take of the first 747, jumbo jet were all over the world.
