Big deal. Flew my training jets. Many years later flew my solo cross country to get my license. We had no GPS system telling us where we are. We got there anyway. Anon used to drive his car with a map to get to a new place. Got there with paper maps and never needed a map again to get to that place. Today: Oldanon has GPS so ask me to get to a new place again and I can't remember .
Anon says throw away GPS systems and let us use maps and when in the air, have a control center who has you on radar. We don't need no stinking GPS.
