Corrected entry: When Cal and Joe are approaching the airfield early in the morning, you can see the wipers moving. But as the jeep pulls closer into view, you can make out through the fog that Cal is moving the wipers manually himself.

Correction: I don't see how this is a mistake. Cal and Joe are in an old military jeep that have hydraulically powered wipers. But if the hydraulics go out, they can be operated manually, which he does.
