Object appeared slightly east of rt 183 1 mile north of gonzales tx, traveling due west at a very high rate. when i crested the hill and was able to see the object again, i saw 2 of them, apperared to be in a formation were one was lower and to the right. they were completely out of sight in seconds. talked to ken atg the san antonio office, he told me to file this report. i first thought it was an ultra light plane by our little airport, but quickly realised it was big, the i thought...Man is that thing booking accross the sky. then i saw the other one. no time to react...Soooooo fast!
