If it was a plane’s contrail, it should be easy to plug in the time and direction of the “plane” and backtrack to LAX or whatever airport to get the flight #, take off time, and destination.

FAA should be able to back track with the above data to determine if it was a plane, where it took off, when it took off and its destination using basic mid school geometry and algebra.

So far we haven’t been told those specifics.

See link at #455 for thread with much discussion and post #115 there :

for the likely flight (US Airways #808 > 08-Nov-2010 > PHNL-KPHX passing overhead just to the south of the Los Angeles area en route to Phoenix from Honolulu).

Now we have a full thread discussing that flight:

Mysterious missile launch most likely US Air flight 808

So far we haven’t been told those specifics.

I flew from the mainland back to Hawaii once while sitting next to an airline co pilot deadheading to HNL. I asked him about air space restrictions over cities and airports and if airliners would have to make course changes to avoid areas like major hubs. He told me 'no', the a/c would just stay at altitude (usually around 35,000') and fly right over; no risk to air traffic on take offs or approaches or in holding patterns below.

I doubt if an a/c at 35,000' can be seen from the ground or even from a helo at 500' at that altitude and if that a/c was producing a contrail, all that would be seen is a wispy streak in the sky. The alleged Hawaii to Phoenix flight would have been at the 35,000' flight altitude passing over or near LAX and all that information is on LAX's control center.

Like so much of what's in the news lately, this doesn't add up.
