It seems you misread my comment. It seems like you understood the first part, but not the second part. I will clarify this for you to help out.
Yes, I watched and heard that part about the oxygen delivery system problems, therefore I wrote:
(1) "further to how the F35 had oxygen delivery problems in manufacturing" [which "they solid mention" in the video], and then..
I also wrote:
(2) "there's a report a F35 crashed and went missing.." [that part which we perhaps didn't hear in the video.]
I think it would've been worth reporting that F35 crash after first mentioning there were reported problems.
