Hi,
Thanks for the info. Here'sa brief summary of the few things that I've seen or read on the matter;
A news helicopter crew spots something in the sky that is said to look like a missile headed towards them, and it is tracked for about 10min.
News reports indicate that no other aircraft crews reported anything unusual that day.
Initially the government indicates that they are not sure what is was.
Based on a CBS News segment in one of the links previously posted, the reporter indicates that although the government can't definitively say what it was, a spokesman did indicate that the government was sure it was not a rocket or missile.
Many people claim that the video/images arelikely the contrails of a transpacific jet.
Many individuals comment that either the images do look like images of known missile launches and/or they do not look like any image that they have seen of aircraft contrials.
Some bloggers post that they believe that the images/video is either the contrails of one of two specific commercial jets heading inbound from Hawaii. To support this, one blogger posts an image from a commercial webcam that is said to show an image similar to stills from the original newscopter video but 24 hrs later (though at/near the same time of day), and from a different angle/perspective.
Others post claims that the images/video are of the launch of a Chinese missile from asubmarine operating off the California coast firing out into the Pacific.
Based on the above a couple things struck me. Specifically, the newscopter pilot appears to have indicated that he thought what he saw looked like an inbound missile. The claims that I have seen about a possible Chinese launch appear to claim that it was fired from near the coast to out over the Pacific, which would suggest a path in the opposite direction noted by the newscopter pilot.
Additionally, if it were a missile and it was viewed forabout 10 min, it would seem that it should have covered a significant amount of ground. Specifically, data on the web for the old US Polaris submarine launched missile suggests a speed of about 8000 mph, which would translate to about 1333 miles crossed in 10min (or a little over 1/2 the distance from LA to Hawaii).
Finally, the image from the bloggers from 24hrs after the initial video/stills appears to show avery similar imagein the sky that is said to correspond to the flight path of one of the two commercial jets previously noted. Since no one has claimed that this is an image of a second missile, it seems to suggest to me that it is likely the contrail ofthe plane the blogger suggests, and thus that jet contrails can in fact appear like that shown in both the originalvide/stills and in the image from 24 hrs later.
As such, baring any new info it seems that the explanation that it was likely the contrails of a commercial jet appears to be the best supported explanation from the info I've seen so far.
Regards
PF
