The jet was something I've never seen before and I live very close to Hobby Airport.
It's layout was t-tail with the engines mounted aft on the fuselage, port and starboard. The wings were low mounted and had an extreme amount of sweep back as did the elevators mounted high on the tail. The nose was extremely pointed and the overall affect of the wings, tail, and pointy nose gave the impression of very high speed. Anyone know what it could have been?
