Keep your knots up.
Involved in a rescue of 3 VFA types a few years ago. The kids of one of the guys we picked up sent a care package to the swimmer that pulled him out. The kids made a thank you letter hand written in crayon. Every person who read it teared up a little.
However I know one notorious VF type (recently released from federal prison) who was never so grateful. I received an email from an old SAR guy just this morning discussing him, that said in part:
"...I remember when we would invite him to HC-7 reunions we had to pay all of his expense's, I guess he forgot that we were the ones that rescued him after he was shot down..."
