Corrected entry: In the beginning of the movie when they go down in to the cellar, Jo's mother lights a kerosene lantern with no prep work done to the lantern. This would be impossible because the mantles can only be used one time and then they have to be replaced. When you put a new mantle on, it has to be "ashed" or burnt before the lantern can actually be used. Then the lantern she was using had to have the kerosene pumped up or 'vaporized' in the chimney part of the lantern. Only then could Jo's mother put a match to the mantle to light the lantern.
Corrected entry: If the base of the twister at the end of the movie is a mile wide, and while attached to the pipes they see the center of the tornado, and the wide view of the two of them hanging on to the pipes after the tornado passes show they are about twenty yards from the house, logic would follow that the house would be taken also, wouldn't it?
Corrected entry: There was thunder being heard as the drive-in movie was playing. The owners may not have known that a tornado was coming, but they surely would have been made aware that there was going to be rain or otherwise bad weather and cancelled the movie. Drive-ins naturally are at the mercy of weather conditions.
Corrected entry: When they are chasing the second tornado, Bill Paxton says something about the tornado being a sidewinder and brakes suddenly, allowing the "bad" corporate team to go past them. However, the six-car "bad" team takes almost thirty seconds to overtake them; indeed, you see the same cars pass Paxton's car two or three times.
Corrected entry: When Jo and Bill are running from and going towards the F5 tornado, there are buildings, semi-trucks, and other things being thrown around and sucked up. Living in Oklahoma and being near a tornado, buildings don't get thrown on the road without taking the trees and cars or trucks around them and a truck would certainly be taken with a Semi. Plus, when they are running from the F5 with all the corn, fences, farm equipment, etc. being sucked up and thrown, they would have been tossed around just as violently.
Corrected entry: When Bill and Jo are chasing their first tornado in the movie, we see the tornado dismantle a barn into several pieces. Later, it goes through the bridge Bill and Jo are grabbing onto. It dismantled a well constructed barn, but barely pushed the truck into an old and rickety bridge?
Corrected entry: Near the end, they tie themselves to the water pipe with leather straps and are lifted upside down by the twister. An F5 tornado would have torn them to pieces no matter what they were tied with, and would have easily broken the leather straps as if they were candyfloss.
Corrected entry: In the "sisters" scene, when they catch the red truck and spin it, why doesn't the truck either fall off the road, wobble around violently, or at least end up in a different position than still lined up down the road? In a real twister and in footage I have seen, even a strong crosswind would not be nearly as kind to a vehicle placed in its path, let alone 2 tornadoes at once!
Corrected entry: In multiple scenes in the movie, you see objects flying through the air like the cow, yet the tornado itself is a good distance away (at least a half mile). This simply isn't possible, in fact, at that distance from a tornado you normally will either have calm air or strong DOWNDRAFTS, certainly not objects floating around. Only in the tornado itself will objects be flying in the air, and they basically will be lifted up, then dropped, as the tornado passes over.
Corrected entry: In the scene where Bill is loading the newly modified sensors (with the aluminum can "propellers" on them) into Dorothy, Dusty hands him the first box and when Bill dumps them, Dorothy appears to be full - some sensors even pile up and spill out. But subsequent boxes are dumped with no problem; Dorothy is not nearly as full.
Corrected entry: At the end of the movie, after the F5 tornado, the horses on the farm seem to be completely unharmed, not to mention well-groomed. Anyone care to explain how they not only survived, but didn't even seem to be affected at all? Even if they were by the house, which the tornado didn't take, the wind would have at least messed up their manes.
Corrected entry: At the end of the film Hunt's and Paxton's characters are lifted and held aloft by the F5 as they hung onto a ground fixture. Wouldn't a force strong enough to lift their body weights be strong enough to rip off their clothes and send them to Oz? Or at least their shoes? Yet after the tornado passes all clothing is present, nothing is missing or even torn.
Corrected entry: In the scene at Aunt Meg's, when the group is discussing the Fujita scale of tornado intensity, they refer to an F5 as the top strength on the scale. The scale actually includes an F6 level; even though that speed has never been officially measured, tornado experts would know it exists.
Corrected entry: As the two main characters are in the twister near the beginning or middle, and under that small bridge, the twister moves away. Debris falls from the sky, and their truck falls just in front of that guy's new girlfriend. She screams and panics. Then all of the other guys run to see if SHE is OK. Why was everyone more concerned about someone's NEAR injury, as opposed to the two who may very well have died in a tornado?
Corrected entry: The first time they try to get the F5 to suck up Dorothy, they watch it roll across the middle of the road. When the tornado winds move it around the pavement, you can see wheels underneath Dorothy, causing it to roll.
Corrected entry: Why is it so important that Dorothy had to be standing up when the tornado passed over it? Either way those little things would have been sucked away.
Corrected entry: Hunt and Paxton are shown running through the corn - wouldn't they have run back in the same direction as they drove their truck when they headed toward the twister? That would have been the easiest path and away from the twister.
