Man is not lost.
Danny - Reference your 7914.
With the greatest respect to your experience I feel that you do a serious injustice to the splendid Air Traffickers at Syerston (no, not Leeming) in the 60s.
No compass, no gyro procedure was always available and regularly practiced but, as I stated, I had a perfectly good gyro which was unaffected and could be selected to DG mode. It was only the flux detector unit which was rendered unreliable by the lightning strike. A subsequent ACR7 recovery with a fairly reliable heading reference was a more practical option.
