Sorry, but it is up to you to prove that they did.
Flt Lt Tapper did not have breakfast in the Mess and went to the Met Office alone. If he and Flt Lt Cook had breakfasted together then they could both have gone to Met Brief - in accordance with standard procedure.
If I had been programmed to carry out a Standardisation, Categorisation or Instrument Rating Test with a crew where only one of the Pilots went to Met prior to a 6+ hour sortie for which no in-flight meals were ordered then there would have been only one outcome and that would have been followed (I would expect) by a one sided interview for that flightdeck crew with someone with 3 or 4 rings on their sleeve.
Incidentally, has anyone asked Lt K exactly what the turning point was - the Lighthouse or the Helicopter Landing Site?
