Efforts to remove lead from aviation gasoline date from the mid-1970s when the first unleaded and low-lead fuels were introduced by refiners in response to the Clean Air Act.

How best to avoid a collision or incident with a UAV today? “Pay attention to the NOTAMs,” advises Kurt Barnhard, Ph.D., director of Kansas State University’s College of Technology and Aviation. “We are required to notify the pilot community 48 hours before we operate,” Barnhard said, referring to the test and training flights KSU students are conducting with smaller surveillance UAVs near the Salina campus.
