This weekend marks 70 years since the de Havilland DH.106 Comet 1 received a certificate of airworthiness. This achievement on January 22nd, 1952, allowed the plane to become the first turbojet-powered civil aircraft to be awarded such a certificate, changing the face of aviation forever.

An I treating piece of history for anyone who didn’t know. The airplane however became a failure after three explosive decompressions happened.

Yeah the square windows meant that cracks appeared in the corners and spread across the cabin as it was pressurised. After many cycles the frame was so weak it gave in. By the time it was fixed with circular windows the 707 had taken over.

I guess it did set the mark on commercial aviation.
