Atomic Twister is a film about tornadoes threatening a nuclear power plant written by someone who has apparently no knowledge of tornadoes or nuclear power plants. I'm not going into the plot here, because it's pretty simple, rather, let's take a look at what the writer messed up. First of all, I was not aware that, in Tennessee, they had "stealth" tornados. At one point, a character makes a call on his cell phone, then turns around to see a tornado about 50 yards away, bearing down on him. In reality, of course, tornados are so loud that one can be heard at least a mile away, if not more. Also, the impending tornadoes are always signaled by high winds whipping around the characters. The writer must have gotten tornadoes mixed up with hurricanes. The fact of the matter is that the air can be quite calm before a tornado strikes.
As for the nuclear power plant, the writer again drops the ball. The characters keep talking as though a meltdown will cause the plant to explode like an atom bomb. That is a total impossibility. The plant may suffer a meltdown and release large amounts of radiation, but it CANNOT explode!!!
All I can say is, watch Atomic Twister is you want a good laugh. Otherwise, stay clear.
