OKLAHOMA CITY—There were some tense moments at the Mike Monroney Aeronautical Center Monday morning after Hazmat crews were called to investigate a suspicious letter.

Officials say a worker in the mail room was sorting letters when he patted an envelope and noticed a white cloud coming from it.

That’s when the worker immediately called for the hazardous materials unit to come out and inspect the letter.

Luckily, it turned out not to be dangerous.
