According to Brad Smith, RT's son, Greg Boyington was more popular than the myth suggests. Many people thought he was a very very good fighter pilot. Several people agreed that he should have been made squadron leader after Sandell was killed. And when he wasn't drinking he was a hell of a swell fella.
Yes he had issues, but so did several other AVG Pilots, they were board, lonely, far away from home without decent facilities, under attack, in a war zone with weapons and alcohol.
He seemed to be resented by those people who had positions of authority in the AVG because he wasn't afraid to speak up, and of course thise made him feel persecuted, which made matters worse.
Also, Charlie Bond liked him.
Whom of the AVG have you chatted with? I've had several conversations with Erik Shilling, and was saddened to learn he passed.
