Toxic Chemical Spills In Florida & Nebraska

On May 19th, an unknown chemical was released in the Fort Lauderdale airport, sending five people to the hospital. Police have yet to identify the substance. Strangely enough this is not the first case of a "unknown chemical" spill. In the Louisville State Recreational center in Nebraska a train was reported for it's "propane like" smell. The recreational area was evacuated. The unknown chemical substances has yet to be identified. Considering the fact that this happened within a day of each other makes me think that this is not an isolated case.
