The streak is a radar streak which is due to weather radar backscatter. It is not uncommon with sensitive radar available today. If you look closely, you will see the left part of the streak points to a location on Long Island. This is the Upton, NY weather radar location (which coincidently looks to be located at Brookhaven National Lab). Here is a link to detailed discussion of such streaks and other anomalous images.

that’s what I was wondering,t oo, but the time stamp on the radar...

It was 10 minutes later, but with condensation?

I think your explanation is closer, though

kind of curious how it is on two separate radars, though! :)

Here is an image from the sources that you cite:

But still, what are the chances of RaceBannon seeing a shooting star going East to South East in the same area at about the same time that the 12-29-08 21:40 EST Upton, NY radar image shows a streak?

At this point, I'm more likely to agree with the shooting star theory than to with the weather radar backscatter theory to explain what happened last night.
