Taken in 1981 at the Intenational Air Tattoo, Greenham Common, Berkshire.

A slow banking pass by the world's first commercial jet airliner. This a later developement is the De-Havilland DH.106 Comet 4, and was delivered straight to the Royal Aircraft Establishment, for use as a flying testbed, an eventually it scrapped in 1997.

Unfortunately the Comet wasn't a commercial success, due to a weakness around the fuselage window frames, that wasn't discovered until after several fatal crashes. The fault was soon found and rectified, but didn't help with sales.

Following the container under the fuselage, is this a Nimrod?

No, this was a De-Havilland Comet. The bulge under the fuselage was used to test equipment for the Nimrod, and other aircraft too.
But essentially, the Nimrod was nothing more than a modified and updated Comet.

Thanks! Yes, the Nimrod was a military comet. Her long career is the proof that the Comet was not completely wrong constructed.

The phenonmen of material weakness was unknown before, so they didn't do something wrong from this point of view. Of course the crashes were a tragedy, but it raised the security in air traffic.

Actually the material weakness was caused by the rivetting round the window frames. That caused stress fractures as the aircraft flexed in the air and eventually led to the window and frame blowing out, which led to a massive stress fracture across the whole airframe.
