I’ll take one.
These are single-engine. 1Z is twin.
Last transmission was that they were returning to base after supporting a dustoff. Two weeks or so listed as an MIA until a patrol found the remains of the helicopter. He always told my dad not to worry about him getting taken prisoner. He said the cobra was nothing but fuel and munitions.
My best friend and hunting buddy was a Cobra pilot in Vietnam.
He died 12 years ago, one week after finally receiving a silver star for retrieving a downed Cobra Gunship from behind enemy lines. He hiked several miles to where the chopper was down, got it started and although leaking oil, limped it back to base in a dozen or more small hops. He could not fly it more than a half mile at a time without over heating, so he took it in half mile steps, landed it and waited for the engine to cool enough to continue, which was just about as long as it took for the VC to catch up to him on foot between hops.
