Interestingly enough, my dad flew through tstms in peacetime for the AF.

He was in the initial cadre of instrument flying instructors at Barksdale AFB when it became HQ for Air Training Command. He wrote part of 51-37, the instrument flying procedures manual.
One of the chapters he and his buddies were going to write was "How to Fly Through Thunderstorms". It ended up being a very short chapter best summarized by "DON'T!"
He and others would sit "strip alert" on hot summer nights in B-25's waiting for a good boomer to pop up. Then they'd go fly through it. There are some photos around of severly hail damaged B-25's. Many of those come from this experiment at Barksdale.

He said it was some of the most exciting flying he ever did. But he didn't say that in a way that connotes a good or fun thing.
