I’m not sure about my son’s friend.
My son flew a Phrog (CH-46E) x 3 years, and when it was being phased out then transitioned to the Yankee (UH-1Y) (avoiding a shore assignment). After he was qualified, he went right back to the Fleet for 3 years, and is now completing a billet as an instructor pilot at MCAS Pendleton.
We’re awaiting news of his next assignment.
