www.devilfinder.com Vietnam Helicopters they just vibrated to pieces

My eight years older brother (he passed away at Fort Ord,California in
1966) was a Helicopter Mechanic at Vung Tau in 1964,same year I was in
Vietnam.You talk to anybody who was a Mechanic on those Helicopters and
they will tell you some of them crashed because of vibration,some of the
Pilots will tell you too.
