(They have been exposed to 140–150 mph (225–241 km/h) winds in actual storms.) "Confirmed" At a Michigan airfield used by Kalitta Air, the group used the engines of a Boeing 747 to generate the needed wind forces and speeds, with a vehicle positioned directly behind one engine’s exhaust. The first test was carried out at a distance corresponding to 160 mph (257 km/h) winds (mid-EF3 tornado range); a passenger car had its hood torn off and was pushed back 50 ft (15 m). The Storm Chasers’ vehicles, TIV2 and Dominator, suffered no damage in this trial except for TIV2's door flying open because Sean had forgotten to lock it. Each vehicle’s anchor spikes allowed it to keep its position on the ground. In the second test, the vehicles were placed so as to feel the entire 250 mph (402 km/h) wind. Within seconds, the car lost its hood and was thrown backward 250 ft (76 m). TIV2 held its position, while Dominator slid across the ground but did not tumble due to its low profile that kept the wind from blowing beneath it. The only signs of damage were a bent anchor spike and a twisted license plate holder, respectively. Noting that an occupant in either vehicle would easily have survived, Adam and Jamie declared the myth confirmed and stenciled their seal of approval on each one. It is possible to build a personal tornado protection device. "Confirmed" Three criteria were chosen for testing - portability, degree of protection against flying debris, and ability to withstand up to 135-mph winds (the equivalent of an EF3 tornado). Adam and Jamie worked on separate prototypes: an inverted bowl topped by an airfoil to push it into the ground, and a low-profile tent with an anchored base that could pivot to face changing winds. Jamie’s design performed considerably better than Adam’s and was chosen for full-scale testing. A prototype built from polyethylene, aluminum, ballistic nylon, and duct tape was taken to the Kalitta airfield; it could be folded up and carried in a backpack. For the debris test, Jamie fired wooden cylinders at the shield, using his soda-can launcher from "Cup vs Car". Buster and Adam each took a turn inside the shield, with no ill effects. Adam then stood in the 747's exhaust until he lost his footing, which occurred at 130 mph (209 km/h). This wind speed was used as a minimum that the shield would have to endure without any injury to Jamie inside. It tore apart at 135 mph (217 km/h) due to failure of the attachment points between the panels. After these were redesigned, Jamie was able to hold his ground in 180 mph (290 km/h) winds – the equivalent of an EF4 tornado. ---------- --
