I know this is going to sound crazy (so, what else is new?), but I think the meteor and the contrails are coincidental and unrelated. The bright flash is typical of a meteor, which would not leave zig-zagging contrails. The contrails presumed to be left over from the meteor were visible an hour later and were not characteristic of a meteor trail. Below is an example of a contrail taken in 1996 looking east toward White Sands, NM.
