Just a guess Sherm, I don't think there was anything wrong with your post. It received some well thought out replies.
All except one.
We all know who the troll is. Not a pilot, or even in the industry, but gains some sick pleasure from throwing rocks. Obviously out of envy.
I exposed his little secrets
here a while back and he quietly retreated back under the rock he crawls out from for a long while. Now he's decided to crawl out again.
I'd say the mods could see your thread degenerating thanks to his trolling. Quite why they don't just ban him completely I'll never know.
