1 who sets and how it is set for the FDR?
2 how are times written down for this, in a log, turn around look at log, write down time, ??? not enough to know why on 2
3 how long does it take for sound to travel thru ground? is the time ajusted for the data traveling thru the ground or what!!! why would the readings match the time, it takes time for waves to travel through the earth,
4 are they in sync, how do you know, are you answering your own question
Time, need to know who set the clocks
but then this is only an issue for CT nut cases who think a plane did not crash in PA, since there were two planes and radar data as witnesses, it seems the only people who really can use this 3 minute non issue are misleading CT minded people
Explaining why my clock is different than your clock or their clock is not very hard to explain, but I guess CT guys make up stuff anyway. It is a waste of time trying to help them, they will not believe it is possible a clock can have the wrong time
(PA has a time warp in this area due to the depleted coal that use to hold the time space continuum in check)
