FSI is an outstanding company to work for. Their commitment to instructional quality is absolutely first class.
FSI is the major instructional facility for the Embraer 170 series aircraft here in the US. All of the 20+ sim instructors have major airline experience...primarily TWA. Most of the TWA folks are former TWA training center instructors...either line or simulator.
We're all based here in STL...come on down and have a chat with us. You'll like what you hear.
