Here's a movie of the progress made toward Sevastapol:

Excerpt from "Spectre Gunners":
Arriving at the aircraft, tail number 623, he opened his checklist to a specific emergency page. He deliberately dropped the checklist. Picking it up, he opened it at random. He was satisfied that there were no evil omens. This is the procedure he had adopted following one particularly harrowing experience some three months ago. This was the procedure that comforted him. Somewhat.
He flipped to the preflight page and began his walkaround. There was a large, yellow, noisy, power cart plugged into the left side of the aircraft, so he put his earplugs in.
Both the 20-mm guns looked serviceable. The 40-mm gun was okie dokie. The 105-mm gun was a go. He jumped up on the ramp and was making his way forward, checking his gear, pulling on this, tugging on that. He had to do that to make sure it was snugged down good and tight. It was part of his procedure. He had made it all way to the 20-mm guns in the front when some officer appeared in the doorway to the cockpit.
"Hey, get off the damn plane. I'm aligning the INS. Gimme about ten minutes."
Haberkorn held up both hands in surrender. "Sorry, sir."
He walked slowly, carefully, not quite tip-toeing, to the ramp.
"Sheeeeeiiiiit, now I gotta start all over again" he said to himself.
He started again, in front of and facing the plane, opened the checklist to the emergency procedures page and purposefully dropped it on the ground. He picked it up and opened it at random. Satisfied, still no bad omens, he started at the forward 20-mm gun looking stuff over again, exceedingly slowly.
See what happens, Hab. This is why you gotta come in so early. This is why you gotta start so early. You gotta allow enough time to do it right. Make the perfect walk-around. A perfect walk-around and nothing can go wrong.
Over an hour later, he was through with the pre-flight. He had had to start all over again one
more time because the flight engineer asked him to 'come over here and gimme a hand with this' and he had done it. But the pre-flight was finally over. He could go inside, cool off a little, get a drink of water. The brief was to start in twelve minutes so he thought he might as well go sit in there.
I read somewhere that humans eat more bananas than monkeys and I believe it's true because I don't remember the last time I ate a monkey.
