Island In The Sky (1953)

Continuity mistake: While the close-ups showed heavy ice build-up on the doomed plane, the long shots showed no ice at all.

Visible crew/equipment: When the search aircraft make their last fly-by over the Duke and his crew who are supposedly stranded on a frozen lake, parallel vehicle tracks are plainly visible, leading to their aircraft, and around it.

Revealing mistake: When ice is shedding from the plane's wings, the chunks slowly slide forward and then down the leading edge. Loose chunks should have flown off rapidly to the rear due to the airflow.

Capt. Dooley: Tell them we're in a jam. Loosen up and lose some altitude. We're turning North West until we run out of gas.
Pilot: But if we go North West Captain, we'll fly right off the map. It says "unchartered" up that way.

Capt. Dooley: I know you're down in the middle of a big nowhere. They're all dependant. I ate today and it's still strong. But tomorrow. So find food, that's number one. Find out where nowhere is, that's number two. And you can help the others find nowhere. They'll come, they won't leave you alone waiting on a pin point of nowhere.

Capt. Dooley: I'll shoot the first one of ya to leave camp. I'll aim for your legs. I may miss and hit ya in the back of the head. Either way serves ya right.

Question: Why, after days with no food, would Dooley throw away the box of Spam? I would have been ready to eat the box!
