I don't know whether I ever encountered a trans person in my line of work, but white lab oats are a great equalizer, and it is hard to display in them any gender identifiers (except the hair).

I never was interested in being a pilot, but I was never interested in being a train engineer or a truck/bus driver either!

I've observed MTF are often overachievers drawn to highly technical/challenging fields. Pilot/engineer/IT are just one of many. Many choose military service. Whether it's a sense of duty, service mentality, a way out, or to disprove gender issues varies by individual.

Oh and I fall in the IT/pilot (private)/Military crowd.
