”ちっとも飛んでない” Meaning in this context


In Episode 40 of the First Gundam, Amuro and Sayla have this conversation:

> セイラ 「そうよ、アムロはニュータイプですもの」
>
> アムロ 「タイプから言ったら、古い人間らしいけど」
>
> セイラ 「フフ、そうね、おセンチで、ちっとも飛んでないのにね、アムロって」
>
> アムロ 「そう正面きって言われると、いい気分のもんじゃありませんね」

I'm confused by Sayla's second sentence. Is there any slang meaning for tobu
that doesn't relate to flying? Can Osenchi in this case also refer to
centimeters instead of sentimentality?




Looks like this 飛んでる/翔んでる is an obsolete buzzword (in 1970's) meaning
"freewheeling", "liberal" or "having different sensibilities (than the older
generation)". Unlike
[ぶっ飛んでる](https://jisho.org/word/%E3%81%B6%E3%81%A3%E9%A3%9B%E3%81%B6) (which
is currently in use in the sense of "outlandish; insane"), 飛んでる was a positive
expression.

So ちっとも飛んでない means Amuro has a pretty old-fashioned and conservative mindset.
古い人間 refers to this, too (see
[this](https://japanese.stackexchange.com/a/57008/5010)). They are jokingly
saying he is a [newtype](https://gundam.fandom.com/wiki/Newtype) in one sense
but is an "old type" in another sense.

[おセンチ(な)](http://zokugo-dict.com/05o/osenchi.htm) is another buzzword of the
70's meaning "sentimental".
