Reading coverage of the French air force's nuclear exercise (Poker) at the moment I came across this:

In 1966, the AdlA had a serious incident with the Mirage IV QRA based in Orange. A split-flap indicator board - like the classic airport/railway station ones - was used to display alert states via some sort of landline from the HQ in Taverny. Due to a lightning strike, the board clattered round to display "DG" in black on red on one dispersal only, the equivalent of "Scramble QRA", and the crew responded. Their C3 procedures required them to respond immediately to the board and to only accept ad hoc orders from senior officers on site after completing a special authentication. As a result, they ignored efforts by the squadron commander and ops officer to stand them down, took off and escaped from the vicinity of the base, before heading for their tanker bracket over the Alps. Various VSOs called up on the radio but they were also ignored as standing orders required radio silence at this point. However, the AdlA operated a similar positive control protocol to that used in the V-Force - on reaching the bracket the a/c was meant to call in to get positive confirmation of the strike order, and failing that, RTB. As a result the jet returned safely after either burning off or dumping fuel.
A couple of interesting things - their SOPs seem quite similar to British ones notably the centralized telebrief-like C2, the requirement to treat ad-hoc orders with suspicion (this comes up in several stories in the various V-threads here), and the positive control procedure. In other ways they weren't - note the indicator board rather than the voice of the Bomber Controller. Apparently de Gaulle was unexpectedly pleased as the crew had responded without hesitation and had followed the SOP strictly in not listening to someone randomly waving his hands on the taxiway or begging them to stop on the radio.
Of course France had some very good reasons to worry about a senior officer turning up and trying to give direct orders to the aircrew - this was only 3 years after the 1962 coup attempt in Algiers.
