Celebrating the 50th anniversary of the Boeing 747's first flight on February 9, 1969, we present four videos of the final version of the 747 - the dash 8. These are of the freighter model which has the original "hump", not the extended one which seats passengers. The upper deck of the Boeing 747 has been stretched twice - one on the -300/400 and then again on the -8 Intercontinental. READ and SEE of our 747 50th coverage. We have added a fifth video of the 747-8I's first flight at the end of this story just for comparison. These testing videos cover, minimum up-stick to establish the slowest take-off speed, extreme braking to test the brakes, G Loading to test the wing strength and finally a duration test.
