My 210 (Non Turbo) story.
Way back when I was flying canceled checks (remember checks.??) I was between Tampa, FL and Mobile, AL, happily cruising at 6000 msl. There were thunderstorms popping up everywhere. There was some sort of RADAR in the 210. It was not a Bendix unit. It had a screen shaped like a drive in movie parking with red, yellow and green lights to show the level of the thunderstorm.
ATC was doing a good job of vectoring me around, then notified me about some level 3 and 4 thunderstorms building in front of me. He said they were only about 10 miles wide, so I opted to go through them. The DO of the company told us to go through thunderstorms. I told him to FO after that Well, in just a few short minutes they went to level 5 and 6 and now embedded. Too late to vector around because now I am in the middle of it all. I asked for a 2000 feet block of altitude which was approved. I reduced power. I reported the turbulence as severe for me as I was being thrown every which way but inverted. A regional turbo prop came on asking for a ride report off shore. The controller just told him there was a 210 in that area reporting severe. So he opted to deviate to the north. I was really being thrown around, so I asked for a 4000 feet block. The controller just told what ever I need, just do it, no need to ask because I was the only plane in the area, I think I heard him say only dummy in the area...
So for the next 100 hours (ok, maybe 45 minutes) I was tossed, turned and thrown up and down with 2000 foot altitude variations. I was thrown into 90 degree banking several times, and then thrown into a 90 degree banking the other way. The stall warning was sounding off like a trumpet. I did not try to hold altitude or heading, I just concentrated on keeping the wings level, or at least to not go inverted. My flight bag was strapped down on the right seat. My keys were in a little pocket on the inside and held closed with a small piece of Velcro. My keys came out and hung themselves on the ear piece of my sunglasses. Until my headset and sunglasses went flying off my head. My lunch and water bottles were flying around the cockpit.
Then suddenly I saw something. Blue sky.!! The ride improved enough to retrieve my headset. ATC was very relieved to hear from me. I reset my GPS and was 86 miles almost due south of Mobile Downtown. Over open water. Needless to say I quit that job several times in the last 30 minutes of flight. Unfortunately I still had to go to Mobile Downtown, then the final leg to Bessemer, AL.
That experience made me a big fan of the 210.
Not long after that I went back to Alaska, north of the Arctic Circle where there are no thunderstorms. Cold, snow, wind and darkness but no thunderstorms...
