In the early 90s I was in an armor unit and got a tornado safety breifing. Question: If you are in a main battle tank and a tornado is approaching you, where is your safest place? I answered, "Hell, in a damn main battle tank".
Wrong answer. Lowest possible area, preferably underground.
What?!
Reason was that main battle tanks do NOT have their turrets attached and if picked up or rolled, will probably separate turret and hull.
Safety officers showed us pictures of overturned tanks and 500? ton locomotive engines overturned and blown 1/4 mile away or more (basically rolled with tornado).
Andover KS tornado happened later and we rolled in and made me a believer in preps for tornadic weather.

And have you seen the footage of the Andover tornado going from a wisp touching the ground to a huge thing opaque more than a quarter mile wide in about 20 seconds?
