PITTSBURG, Kan. —  For the past couple of months, three teams of southeast Kansas middle and high school students have been hard at work planning drone missions and the placement of portable obstacles to use in those missions in a 10- by 20-foot drone arena. The competition they’d been preparing for finally took place Thursday at the Pitsco Idea Shop at Block22 in downtown Pittsburg, with a team from Fredonia Middle School narrowly beating teams from Frontenac High School and Fort Scott Middle School. 7th grader Noah Howard, a member of the winning team, said he and his classmate Wyatt Raine are taking a robotics class at school, and got interested enough in the subject to start looking for competitions to enter.
