SFFP
I was merely quoting the BOI regarding catering. They concluded that the crew would have eaten only a few biscuits during the first sortie. There was no record of Flt Lt Tapper having breakfast and no crew meals were ordered for either sortie.
Thus, when they departed on that final sortie, the Co pilot and ALM's had not had a meal for some 10 hours and the Captain for some 22 hours.
You may recall that changes were made to ensure that Aircrew had breakfast before flight.
