1999-07-25 - Verhalen (between Balmorea & Pecos, TX - Diamond

High speed low altitude pass from east to west at approx. 500 ft high.after passing to the left made 45 degree right turn and vanished.

On Sunday 25 July after returning from scuba diving at Balmorea State Park Texas I incountered a very strange object.We were traveling north on State hwy 17 about 12 miles north of Balmorea Texas.It was about 10:30 pm when I looked up and noticed an aircraft moveing very fast from right to left very low to the ground. I applied the brakes and came to a stop afraid of the sonic boom from the craft. I have worked in the aircraft, airport industry for 17 years. I have hours of experance watching aircraft at night. This was like no siloett I have ever seen and it was not a current stelth ac.It had a diamond shaped body with a sharp long nose. As it passed it occured to be that it had no standard ac running lights Just several red glowing ports on the sides. It was about a quarter to half mile in front of us and never at any point made any noise. This is very flat land and a still dark night it is impossible to not hear engine noise(jet or piston). Now this is where it got very strange. As it passed to the left at about a 45 degree angle it turned right about 45 deg so it was almost going away from us, as it turned it had to very large yellow light side by side on its rear.They were much to large for standard size jet engines. To put in in perspective if you were looking at the rear of an f14 tomcat the light would be about 16 feet across each about 5 feet apart. After about 5 seconds it just dissipeared I mean poof it was gone. After much dicussion we both decided we had just see a UFO. Also going back a week later there are no valleys or mountins for it to get behind except due south of our location. We could also see the lights of the city of Pecos behind the craft. There is just no place it could go. Anyway thats it and I would be glad to speak with someone on this subject.
