I am told,
BTW, that several radar operates in planes in the last war
were killed when the plane had a heavy landing, the radar display CRT
imploded, and they were litterally shot in the face by bits of the
electron gun.
Not something I'd heard before - but I can certainly believe that; such
displays tend to be pretty large in diameter and of course are
flat-faced so must be naturally pretty weak toward the centre of the face.
Actually, no. The standard radar CRT over here at that time was the
VCR97. That's a 6" diaameter thing with a fairly convex screen.
(Incidentally, VCR stood for Valve, Cathode Ray, or so I am told).
ObClassiccmp. After the war, there were a lot of VCR97s sold off as
surplus. And that was the CRT used for the Williams Tube memory on the
Manchester Mk 1.
