Meyer did not and could not have seen a "shootdown" of the 747 at 13,800 feet only 3-4 seconds before he saw the huge fireball explode in falling wreckage 6000+ feet lower in the sky.
Thanks for belatedly admitting that you heard witness Wire on the radio and cannot verify what you earlier said he said.
"Here is my transcript of an interview with Mike Wire on WABC radio 770 AM on 8/23/2001" - So far we've got one witness - me - to Wire's interview, and none contradicting.
