Before invention of satellite location system, it would be difficult for pilots to fly directly to their destinations.
Then, compass and communication with ground staff were nearly the only way to know where they were.
In such a situation, it's impossible for passengers to know their locations on board, which would have decreased my entertainment on board.
Our safe and enjoyable flight owe to an accurate location system of the aircrafts.
