“When I was hired to work at the Kitt Peak National Observatory (KPNO), it was not disclosed to me that the site was being hit by powerful sonic booms from military supersonic aircraft that would shake the buildings. I had noticed that there seemed to be a significant number of staff that were having heart issues and some appeared to have had heart attacks and died prematurely. I later discovered during researching my own heart issues that it was a suspected effect of exposure to sonic booms. Regular exposure to sonic booms from military supersonic jet aircraft is suspected of increasing the incidence of vibroacoustic disease, a thickening of heart tissue which may lead to heart arrhythmia or premature death.” MilitaryAstronomyAirplaneObservatoryPeakNationalKittSupersonicBoomsSonic Author:Steven Magee
