I've seen them as well for the F-117. But that's what I mean by becoming excessively reliant on tech.
Previously, the location was painted on the floor in numbers for certain hangers
For some reason I thought those marked coordinates were for input for INS initialization? Some GPS receivers will accept a Lat/Lon input to speed satellite acquisition (never messed with a mil-air unit), but that is still a lot slower than a warm start, let alone already locked up.
