Brian// PLEASE clean up your act!!  E=MC squared is a joke,,  ok"OK",   We are not locked into the speed of light #1.  #2 his wife came up with  that formula!!,  all it says is that we cause matter to exist if we travel at the speed of light X 4,  BS  and you know it!!!   Stop the crap..  We have magnetic fields that we never new existed  IE:  The "B" field of a magnet, (the center of a magnet), that has shown us the way to anti gravity... Please wake up...!!!  Just how do you think our government took down the 911-twin towers??  I know you know how,  EMFF.  It was the design by Nicola Tesla.  THE Electromagnetic Force Field,  that's why there was only 20ft of debrea from two two hundred foot steel towers, , to top that off the numerous auto's that were destroyed blocks away!!   and the steel frame for the building just across the street had to be replaced..   As a pilot and Ex military person I really am ashamed of you,  are you getting paid??,(reply>), LOL,(reply>), Thank you ,, we  are on the same page,   Like Tesla said we need to look at things we can't see, that's where the real advancements in technology will come from..  You could put two magnets in the repel mode at 1000 Lp's with a separation of one inch..    WHATS conducting at the center??? in the space between,  I have learned that there is another dimension to magnetic force, almost a mirror image of the fields we see only different in that it reacts to all materials not just iron.. The horizontal rocks found in areas like Stonehenge and others are oscillator stones just like the one at Coral Castle Florida  that allowed Ed L. to lift 30 ton stones..    Looks like the "B" field and a oscillation resonate to the material your working on will give you magnetic lift, (or anti gravity),(reply>), @Rock Lobster  You are correct,  the point was that our military used EMFF to take them down,  the aircraft had nothing to do with the two towers coming down.
