WIDN62,
You are so correct. On several occasions during my few years as an AGE, I have managed to arrive "on base" in the states at OFFS, and completed the B/F, then, usually in the company of the Air Eng and Loady, spending up to 5 hours awaiting the arrival of the "front end". Only to be told that despite our scheduled departure time being 0500L, first take off permitted on that base was 0700L. Once being told that our departure was cancelled, as no flying was allowed from there on Sunday. I bet there are many who have experienced the discrepancy between ATFOC planning and reality. Never mind, it all added to life on Albert.
