Pioneer weather research by Northwest meteorologists led to smoother, safer flying. Chief Meteorologist Dan Sowa led the research work to help pilots avoid clear-air turbulence and low-level wind shear on Northwest's many northern routes over mountain areas. As the originator of the Turbulence Plot program that was a Northwest Airlines exclusive, Sowa was honored by the Federal Aviation Administration for "distinguished service in the public interest on behalf of aviation."
"We're pleased that the enormous efforts we have made over the years to avoid turbulence in the interest of the passenger's safety and comfort are being recognized. It's not very glamorous or visible to the public, but the system makes a significant difference in the experience of flying." Tom Fahey, meteorology manager, celebrating a special award presented by Air Transport World to Northwest in 2000 for its proprietary Turbulence Plot System developed in 1968.
