Unfortunately, it happens. How about this aviator gets into a monster thunderstorm? That can happen easy enough (recent Air France crash in the Atlantic). Radar setting not proper, no radar installed, radar failed, etc.

The pilot didn't think there would be serious weather, and since he's a pro pilot, he checked with flight service, and they didn't see embedded TS's along the route, but they were forecast for later.

So Ace Durden launched (get there-itis), even though the radar was broken, and then starting having doubts... considered turning back, but... boom! In a level 5 cell. All heck breaks loose, like it no doubt did with Air France.

Losing control in a TS / CB is easy enough... living through it, well... if the plane stays together, I guess there's a chance. There would be plenty of wind shear in the microburst !

Rough terrain, sure. Ace, fighting for control, and feeling stupid after 30 years of flying without an incident, is in shear terror as he pops out of the bottom of the storm clouds only to see trees. CRASH !!!

When Delta crashed in DFW due to windshear / microburst, they had at least 30 years of experience in that flight deck, and radar. Yes, it can happen to any of us.
