Great video Barry! And cheers for the info issysuy, makes sense that it was used in TRs rather than Healeys!
Slight drift but vaguely connected: I think Norman de Bruyn should be far better known as another great scientist/inventor. He was one of the main inventors of 2 pack adhesives, paints and sealing, including Araldite, Aerolite and Redux pkus others, and plus thousands of copies of his products around the world, licensed or not!
Redux uses epoxy glue at high temperature and pressure to bond things extremely strongly, including all windows in pressurised aircraft, without Redux Whittle's jet Engine would have been no more than a purposeless curiosity! I know of no cases where Redux has failed in flight! Sadly, when de Havilland was designing the Mk1 Comet jet Airliner they just could not believe that this fantastic new adhesive process alone would be safe, so they insisted on adding metal plates and rivets, and it was stress cracks caused by these that led to the failures. Furthermore, with just Redux, even the infamous square shape of the Mk 1's windows would not have been a problem: other jet planes like the Lockheed L 1011 Tristar have even squarer windows, and no failures as far s I know.
