1990, Op Granby, Tornado GR1.
Returning from a very dark night TF training sortie with a busted radar, we were vectored at 15k into a lively cb by Saudi ATC. Not to recommended. We lost all comms to static and during the turnabout to exit asap the inside of the cockpit started glowing a bluey-purple colour. All of the cockpit & avionics panels eventually had this glow with arcing occuring between the TV-Tabs and canopy arch. Very eerie and it made one very afraid to touch anything.
As soon as we left the cb all returned back to normal and I've never seen it since.
