On February 16th, 2007, a strange happening occurred at Denver International Airport. Within an hour and a half, 14 aircrafts were reported for issues within their windshields. It was unexplainable because some were taking off, landing, and some were even just sitting in place. The NTSB brought in glass experts to inspect the 22 cracked front and side windshields. The Denver Post claimed the weather changes at the time were a variable, and there were some snow and high winds gusting over 50 mph. However, those are typical weather conditions for DIA. Nine of the airlines were from SkyWest, four from Frontier, and one from Great Lakes. 55 flights were cancelled and a few others were diverted. "Airplane windshields are heavily reinforced and designed to handle travel at hundreds of miles per hour and even deflect collisions with birds. It's truly bizarre," Hodas said. "One theory is that there may have been a power surge while airplanes were connected to auxiliary power at the airport gates. Windshields are electrically heated, and a surge could have somehow weakened them. It's pretty unlikely, but it's the only thing we can think of right now," he added.
Whether or not this has to do with the conspiracies is up to each individual. Some believe it's tied in, others don't. I personally don't think it has to do with it, but more information would be helpful to form my final decision.
