My nominee for most accurate aviation explanation of the day (from the
Lancaster New Era ):
Lancaster pilot and Vintage Aero Club secretary John Henderson, 71, said he’s sure Sheaffer and Martin knew they were not supposed to be flying over Washington D.C.
“I’m certain he didn’t know (he was that close to the capital). I’d bet money on that. I think they got lost, which is not difficult to do.”
Henderson said he knows both men and speculated that they just made a dumb mistake by not taking a global positioning system device on the plane.
“GPS makes life so simple for a pilot,’’ he said. “It also depicts restricted airspace.”
But it is up to the individual pilot to take the GPS device along. The club does not have a GPS device for its members to use.
However, the Cessna is equipped with a VOR receiver, a type of navigational radio that receives a signal from a ground-based radio transmitter, said Henderson.
The VOR gives the pilot the ability to determine whether or not he is on course. But the device does not tell the pilot where he is on that course.
That explanation of a VOR is probably the most accurate and most concise that I've seen. It's better than some things I've read in aviation magazines and textbooks.
