“Lots of people know how to use paper road maps, but how many can fold them properly?”
The funny ting is that for pilots, knowing how to properly use/fold maps in the cockpit is an actual tested skill. It is amazing to watch pilots have open charts that block their view.
That's why my next car will have a HUD. ;)
Flying an A-10 before INS was a real challenge. . .1:250 maps required a real map reading/navigating skill and an ability to fold and “juggle” the maps. . .let alone if your flight profile took you from one map to another. . .
