RENO, Nev. (AP) - Environmental groups are opposing an Air Force proposal to extend a supersonic operations area by 1.6 million acres in eastern Nevada.
Critics argue the move would increase the frequency of sonic booms and litter from training operations, harming residents and the environment.
The White Elk area north of Ely is adjacent to the current Utah supersonic operations area.
Opponents say operations would jump from about 400 flights per year to as many as 9,500.
An Air Force environmental study determined the increased military activity would have no significant impact.
Critics say the study is flawed, and want to reopen a public comment period which closed last month.
