DFW, TX 2 Chinooks headed due East...

I'm from the Arlington area and I just saw 2 transport choppers (aka chinook) flying due East. Just a bit South of I-30 which tells me they are flying from Carswell. Now I have seen these things periodically around Carswell. Mainly in Fort Worth and the surrounding areas. However it is a RARE occurrence to see them this far East. They aren't black choppers mind you, but I couldn't see any ID markings. They were at full tilt 30º in hauling ass.

Anyone know anything?
