Mav,
You want to meet aviators in Houston? The Runway club or the The Cockpit if you want to meet airline pilots. In Clear Lake, The Turtle Club or the Town Pump. Big with military pilots specifically, Astronauts. I live in Houston and these are some of my favorite watering holes. All of these places are complete dives, of course. Aviators go to bars to drink and lie to each other not to look at scenery. If the music is to loud then they can't tell each other how great they are or who tonights conquest will be. In other words, don't wear your Sunday best and don't expect a whole helluva lot from the bar interiors. I promise you, you will be entertained!
Semper, Frumby
