Early 80s, GR3 sqn in Germany (not the Happy One). The GR3 was receiving the Phase 6 mod package, one of which was a radalt (no, not connected to anything like the weapon aiming system, just a miniature dial in an almost invisible location). One of the more serious flt lt QWI wannabees was giving this particular briefing. All went well, right up to his last remark which was "Of course, I wouldn't have done it like that. It's pinging away the whole time and it's gonna give us away. I would have left it on standby until the bomb flap was raised, then I would have fired it up". Briefing complete, or so the assembled thought, when a newly arrived pilot, looking perplexed and with his index finger motioning upwards asked "Why would you want to fire a radalt UP"?
