A missal generally has bible passages organized by mass date (instead of in the usual order), as well as some hymns and a reference to the order of mass (the things that happen when you go to church)

Aha.

I was very vaguely notionally Church of England until age 11, although still had to go to Chapel daily from 12-17. I have never been to Mass and I don't really know what goes on in a Mass. I'm not even sure if Anglicans have Mass.

My local Canon certainly had plenty of small-m mass: big lad. Nonetheless, when he scattered my father's ashes in the sea, he got caught by a wave, and proved that despite this he could run backwards up a shingle beach, wearing wet robes, at surprising speed.

I was responding to the framing of the parent comment that suggested "missles", which already essentially ignored that pronunciation.

You said only:

"how people pronounce words ending in that"

You did not restrict which people you were talking about, and that's a critical omission. Nobody in my daily life, in real life where I live or on TV or radio, would ever say "missal" when they meant "missile".

In northeastern US, missile is anywhere between 'ill', and schwa 'ul', but not 'aisle'. "Hurled a miss-aisle" is sometimes heard in court.
