re: Remember when they used to have those signs saying speed monitored by airplane?

They would basically calculate your speed by the amount of time it took you to cross the lines.

Yeah, it's similar to what they used to do at the old SRS bomb plant in South Carolina. They would give you a card at the gate when you entered with the time stamped on it and when you got to the other end you had better be within a certain time window or they'll be wanting to know what the hell you've been doing.

They don't do it anymore, you can just drive through without stopping at a gate at all, or at least on Hwy 125 anyways
