While the crew may or may not have been listed in any given major news outlet’s story presented to the attention span challenged general public, the information is out there and easily findable, thanks to local news sources which have gone on the web.
For instance: http://www.thejournal-news.net/news/local_news/remembering-robert-mayfield-and-the-final-flight-of-mi-amigo/article_a3043722-36b5-11e9-91e5-ff21214aa2d8.html
The Flying Fortress required a ten-person crew to operate, and along with Mayfield was another Illinois resident, navigator Second Lt. John Humphrey. The pilot was Lt. John Kriegshauser of St. Louis, and Second Lt. Lyle Curtis of Idaho was co-pilot. Second Lt. Melchor Hernandez of California was bombardier, Ssgt. Harry Estabrooks of Kansas was the flight engineer and top turret gunner, Sgt. Charles Tuttle of Kentucky was the ball turret gunner, Sgt. Vito Ambrosio of New York was right waist gunner, Sgt. George Malcolm Williams of Oklahoma was left waist gunner, and Sgt. Maurice Robbins of Texas was tail gunner.
The crew named the plane “Mi Amigo,” Spanish for “my friend.” David Harvey, author of “Mi Amigo–The Story of Sheffield’s Flying Fortress,” credits the bombardier with naming the plane.
“Superstition and sentimentality combine in the naming of a warplane,” Harvey wrote. “This one acquired its personality with the help of its Spanish-speaking bombardier. Melchor Hernandez surely did think of the craft as his friend, and the others acquiesced.”
