From experience, I have found myself more alert after a less than healthy food court meal, compared to after a packed sandwich, protein bar, or tuna fish. Who knows why, but I feel more proficient after a Whopper or biscuits and gravy than I do after a salad. Ugh. I am doomed to not fit out the escape window.
Can you see it...? Contributing factors in the accident investigation include failure to follow SOP, failure to monitor altitude, and a low fat diet....
