Advisory Committee

The LETU School of Aeronautical Science regularly collaborates with aviation professionals to ensure our programs maintain the standard of excellence and innovation our school is known for.

Many of these men and women got their start here; sixteen out of nineteen are LeTourneau alumni. Some have worked at one company, started in an entry level position, taken on increasing responsibilities, and now serve as executives. Some served with our country’s military as pilots (including flying Air Force 2), retired, and now fly as civilians. These aviation professionals fly, repair, design, investigate what went wrong in accident situations, and recruit for mission agencies. They manage airports, departments, and companies.

These industry experts bring years of real-world experience to help us hone our programs and curriculum, ensuring that our students graduate with degrees that meet and surpass industry standards.
