Perhaps you are correct but in none of the reports did I hear anything about a high G failure of the O2 system.
Note: An F16 can put some serious G forces on the pilot. My question is what is the difference between the oxygen system on the F-16 as compared to the F-22.
Yes, that was from Nellis AFB. It was the pilots G Suit. I have the link for you.

Could be a small part that fails to the advantage of High-G, but not otherwise like it’s supposed to.
