I started sketching this man during our flight because I loved his profile. Then a flight attendant came over to him and said, “Would it be all right if I told them who you are?” to which he nodded yes. She then announced over the P.A. that “we have an aviation hero on the plane, Gail Halvorsen.” He was even featured in the in-flight magazine in the seat pocket in front of me. Here’s his Wikipedia page. Very interesting.
