Their emotions are in strong contrast to tornado enthusiasts, who, from most peoples' observations, usually appear intrigued, not frightened.

    Of course, to capture a tornado, a number of variables must be correct and you must meet several objectives first.

    Obviously, there must be light (or you must have nightvision). A great number of tornadoes occur during the night hours and probably aren't captured on film due to this reason.

    You must actually locate the area of a storm that is most likely to produce a tornado. The advent of Doppler [sic, it's named after a person] radar has made this task much less difficult. Meteorologists will usually search for the classic "hook and coil" signature that is indicative of a tornado.

Finally, dopplers have not made hooks easier to see - the dopplers provide a lot of *other* information (especially velocity data) that is useful.

      A real tornado chase (as opposed to a lucky catch by someone who lives in the vicinity) involves making a forecast of a target area (not an easy thing to do), driving to that area (often 300 miles or more away), picking the right storm that goes up (most will not be tornadic even if conditions are right), and properly (and safely) positioning with regard to the moving storm.

      Do all of that, and on the average of once out of 7-10 times, you might see some kind of tornado (but most tornadoes are weak and not spectacular - although all are beautiful to the storm chaser).

      The most successful chasers are those who live in tornado alley, study meteorology seriously (whether or not they are meteorologists), spend a lot of time at chase forecasting and driving, and are lucky!

      17280 square inches. Now, for that area to have more than 65 tons of force, you need a stagnation pressure of 7.5 pounds per square inch. Now, what is the stagnation pressure of a 300 mile per hour wind? (I honestly don't know off the top of my head - I'm an EE, not a ME or AE).

      Also realize this: once that tank starts to tip, then the wind is going to get a much better grip on it.

      Being in the eye of a tornado is much like being next to a very large explosion, save that an explosion doesn't keep going on for several seconds.

      True, once you started to move with the winds in the eye, the forces go down quite a bit. But would you REALLY try it? I mean, an Abrams might survive being hit with a anti-tank round, does that mean you would go seek them out? How would an Abrams fare against a half-ton telephone pole at 150 miles per hour? Just the momentum transfer would give you a mile per hour of velocity.

      Also, would you want to deal with the pressure drop? I know a tank is reasonably air tight, but just how air tight is it? And how would your turbine fare with the air loss.
