Yeah he shot down 5 Bettys.
Interesting story, Butch's Dad was mobbed up in Chicago. He was a front man for the outfit and was on paper as an owner of a race track. The story goes Al Capone got Butch his spot at the Naval Academy. Later his old man got into Capone for big money and turned rat on him testifying against him on IRS charges. When Capone was in Alcatraz he finally caught up with Eddie O'hare and on 8 Nov.1939 two of his guys pulled up to O'hare's car while it was stopped at a light on Ogden and Rockwell ave and blew him up with shotguns.
Butch's Dad thus wasn't around for America's involvement in WW2.
Some sources say he only got three.
Alex Vraciu made Betty bombers his number one target after O'Hare's loss. He would practice high side runs at every opportunity.
Completing the circle, just like Butch saved his carrier, Alex later saved his own in similar fashion. Both were named Lexington. The student becomes like the master.
