When you go to the wind science engineering for testing, the requirements are that you have to take 3 shots from the debris launcher at 67 mph simulating a 250mph wind with debris shots of a 2x6 that's about 10 feet long, we passed those 3 shots at various places on our lid being tested and not one shot even cracked the paint. So after we knew we easily passed the FEMA 320 tests that all shelters are supposed to go thru to be certified, I figured what the heck, what can your debris launcher go up to? I was told that the fastest it can shoot is 100mph debris, so that's quite a bit more then 67mph, but we already passed the TTU testing so it really didn't matter it was all curiosity by then, could my door take a hit at 33 mph faster then what FEMA wants?  Well the answer is below, it didn't penetrate the door or even come close! it knocked a little paint off! And we had the testing guys pick the absolute best place on the lid for it to penetrate marked with the laser is the weakest spot on lids. Although this officially means nothing in the shelter world because the 67mph debris shot is all that is required ,we felt pretty good about it and thought we would share that with you! If you were in our shelter and had a major tornado that could throw debris at the lid at 100mph or 300mph winds, the picture says it all! our safe rooms safe pod and porch pod are also all Fema 320 Complaint. Please contact the Wind Science and Engineering Department with any questions of false claims by other shelter providers. We will be adding the actual videos of this shot as well as the 3 required as soon as we get a chance. Picture Below is 100 MPH debris shot(300mph wind) to the lid only, we want to make it clear we only had the lid take the 100MPH hit to see if it would penetrate, The 67 mph debris shot requirement was a cakewalk for our lid. Video Below is the 67MPH debris shot(250mph wind) required by FEMA 320 code Video Below is the 100MPH(300MPH wind) shot that we wanted to see if it would penetrate the lid, this does not add anything special to our ratings of  FEMA 320 Compliance, we opted to do so for our own sakes to see if it would Penetrate the door. We are not by any means claiming anything higher then the 320 Testing, just a fact that 37MPH faster then the test we passed, it did not penetrate our door, just messed up the paint!   Large Piano hinge with stainless steel bolts on one side Other side of lid had 5 solid steel blades in C-Channel with a one handle pull, none of our locking systems are inside the shelter, just the pull lever, not having any part of it in the shelter is safer because there's nothing to blow off into the people inside!   The Fujita scale of tornado violence. An F-5 tornado makes the strongest winds on Earth; Doppler radar clocked one tornado at 318 mph. (In the Fujita scale, wind speed is not measured directly but rather estimated from the amount of damage. Tornado width is estimated by the path of destruction -- which can be up to one mile wide).
