S76Heavy,
From my experience, it does seem that lax flight standards are inextricably linked to morale. But I think it more insidious than that, if it were just morale then one would expect just the OTP to nosedive and the amount of fuel carried to go up. But what was happening was also during the critical phases of flight. I believe this indicates a kind of mental exhaustion related to the extremely fluid situation we find ourselves in with no communication or contact with management until something undesirable happens.
