Two rules questions inspired by NFHS test

[teebob21]

So here's what I think on the scenarios.

1) This is a fair ball. If the same ball was elevated straight up when touched, part of the ball is over fair territory.

2) I am fine with all of these outcomes, I just wish the rules and definitions would be aligned. By rule, a ball that strikes the fence is no longer in flight. There is a line in the book that explicitly calls out the fence as an object which grounds a ball...I saw it during the test and during the drafting of this OP post which I can't find now (unless I dreamt it).

Edit to add: ironically, I had this play a year ago at HS districts. Ball was hit off the tubing, caught by F8 in the air, and thrown in. DHC wanted an out; OHC wanted a home run. Neither got what they wanted.
