I spent a bit of time in Helo's, two types Warrant Officers, and what were called Spec 4 with a club card. Always trusted the older Warrant Officers what had time in Nam. Did one auto rotation in Honduras when a chip light came on. Not something a Navy guy was comfortable with in an Army helo.. Spent about 8 hours in a very confused farmers field. That was after the pilot got lost going back from tiger island to Soto Cano.. Younger than my 34 years, A Spec 4.. Pilot.
