Anthrax scare in Muncie, Indiana

The Academy of Model Aeronautics in Muncie, Indiana was forced to close its headquarters and museum Friday following the discovery of a suspicious envelope containing only white powder.

"The consensus was that this was pretty much a hoax, but in this day and age, until we find out what it turns out to be, we erred on the side of caution," Jim Cherry, the executive director of the AMA, told The Star Press.

The envelope was taken into the possession of the county police, who arrived at the scene at 8:30 in the morning. No hazmat, fire or emergency medical services personnel were called to the scene.

"We followed protocol and contacted the state's homeland security," Jason Rogers, director of the local emergency management agency, told The Star Press. "The sheriff is investigating the envelope and has possession. They are holding it to see if they need outside resources.

"There is no report of any illness."

Staff at the AMA, which employs 55 people, were sent home for the day as a precaution and the building was closed until further notice.

The AMA, a non-profit organization, is the world's largest model aviation association, boasting a membership of more than 150,000 people. The organization promotes the development of model aviation as a recognized sport and worthwhile recreation activity.
