In world war 1 certain kind of pillars were used to guide war planes in India & Bangladesh. pls gv names & inf
the pillers had 3 black stone kind of head that linked to one body. it creates magnetic field. no radio, clock or electrical items works around these things. they were kept under the ground. pleople says the during war times planes used to fly over them. and the government says the they were there to guide planes. pls give me as much information as possible. if possible, a picture as well. thanks!
Answers:
This would have been WW 2
The black stones were probably Swedish Iron.
The tri polar arrangement was done to make their mag' fields more prominent. South to south for instance.
In the plane a sensitive compass would veer left or right when approaching them and would enable the pilot to null the plane.
This would give him direction onto the next marker allowing for drift and elevation.
Really it was a radio beacon stone age style.
I have outlined my theory.
I have never heard of them until now but it is a practical solution to stop radio contact over a jungle that goes on for ever.
I was demobbed from Singapore after the war.
are you sure this was WW1? It would certainly not have been any device that advanced in WW1 also I am not certain that there was a IFL system even in WW2. It could have been one of 2 types of technology used in WW2 either a RAdio Direction And Ranging machine (RADAR as it is known today, the reason being shown by the capital letters) or, and this is the one I suspect, the allies had a device that send out pulsed beacons to bombers, they would fly along one pulse and when it met the second pulse that would be where they would drop their bombs. It was, I supose the first instance of the guided bomb, except the airplane itself was guided rather than the bomb. Hope this helps.
Sounds like a legend to me. There were a variety of radio guidance ranges developed for air navigation in the late 1930s, but most of the description you give sounds fanciful, and does not seem to describe any of the apparatus that were in use.
Sounds more like parts of a 4-arm HF Radio Range than anything else. The ground station was based on an array of wooden or steel poles, but it did not produce anywhere near enough power to disturb radios or clocks.
You might try a search on "radio range" or "radio navigation history" or "instrument flight history."
