In 1954 I left Billings and joined Naval Aviation.
After leaving the service having flown in combat from aircraft carriers and losing many of my fellow aviators -- some of whom became POWs -- I never saw or heard any of my shipmates disrespect the flag. Now I am very curious, do any of these NFL/NBA athletes even know why they are kneeling? If they need a cause, maybe it would be nice of them to send some of their millions to Puerto Rico.
The only time I ever kneeled was during times I presented a folded American flag to the widow of a fallen comrade.
