Comets were the first passenger jet airplanes to cruise at 800 km/h and an altitude of 33,000 Ft.
I still can remember how deeply impressed I got by this elegant airplane when I first saw it landing at Buenos Aires Airport, being a little child!
The initial success of this airplane got unfortunately stopped after a couple of crashes caused by lay-out faults that lead to stress-cracks in the cabin. Once the 2 years long investigation ended, the new series of Comet, called 4A (short range) 4B (middle range and 4c (long range) were built.
In the same period Douglas and Boeing launched the DC-8 and B707, which eventually won the favor of the public.
Forty-eight years ago (June 27th, 1958) was the maiden test flight of the first Comet 4B. Some months later, this airplane made it´s first passenger flight from London to Tel Aviv.
