Writing in the Princess of Mars series he describes flying craft equipped with a directional needle that can be set to point to a desired destination -- then it's just follow the needle, guys.
Any pilot will recognize this as a description of the NDB which has saved thousands of planes and lives over the decades.
This is the same Burroughs who invented Tarzan, writing in the early part of last century.
The NDB came into wide-spread use in the 40's and 50's of the same century.
Notes: NDB confusingly stands for Non-Directional Beacon which refers to the radio station it gets tuned to. This also differentiates it from the VOR which gives a different sort of indication --
to make sense out of that one, you have to know were the radio beacon is located.
