Dead reckoning still has its place. We once had a pilot call in and say "Help,
I'm hopelessly lost over Gravette, Ark.". We all looked at each other, and
after a chuckle, the controller for that area asked the pilot "If you are
hopelessly lost, how do you know you are over Gravette, Ark.?" The pilot said
"Because I'm circling the water tank and it says Gravette, Ark."!! (The town
was too small to be on his sectionals).
