Authorities say a 38-year-old St. Louis woman talked her way past a security guard and entered the cockpit of a private plane at an Illinois airport before she was caught and taken to a local hospital for observation.

Police in Sauget (Saw-ZHAY), Illinois say the woman entered a 20-seat Global Express jet on the tarmac of the St. Louis Downtown Airport about 4 a.m. Wednesday.

Sergeant Vito Parisi said the woman had started driving to Lambert-St. Louis International Airport but instead wound up at the smaller air field in Sauget, Illinois. The plane, which is owned by a Hong Kong bank, was disabled.

Local prosecutors are reviewing the incident to determine whether to file criminal charges. Officials don't believe that the incident was connected to terrorism.
