Many moons ago (two years after the aforementioned incident) I was flying along WITH THE RADAR ON headed south on the Victor Airway towards Baton Rouge. We were following a Bonanza at the same altitude.
Ahead was a tall boy in a line of tall boys but it wasn't painting on the scope. Bases were 1000 feet, which is pretty common down on the Gulf Coast.
ATC couldn't give us much information and after some discussion with the other pilot we decided to deviate west. That particular cumulus cloud just looked violent. Everything was bright white in the blazing sunshine but we decided to go west anyway. The Bonanza pilot told ATC he wasn't painting anything and would proceed on the airway. The Bonanza hit the ground in four pieces.
Radar is A LOT better now and there are multiple sources of information in the cockpit we didn't have back then.
In the previous incident I was pissed at ATC because they were strongly recommending particular headings to me and the last one they gave me put me square into a ball buster but as it turns out they were going to turn me a few more times but the tornado evacuation cut off comms. Yes, it was my own damn fault but I was in my first year and couldn't smell thunderstorms quite yet (I did learn though... Use ALL your senses when dodging the big ones)
And, no, I didn't have radar and, yes, I knew I was heading into a squall line of death and , yes, I did it on purpose.
On that particular run it was pretty common to punch the same squall line twice. A few times there were two squall lines 75 miles apart and I punched through them both twice. I was 20 years old and invincible.
We used to do some wild and woolly stuff back in the last century.
I am enjoying the sanctimony of the young pups on PIC responsibility in this thread.
