The Meadows Field Airport in Bakersfield, California was shutdown on Tuesday by bottles of honey. They did not know they were dealing with honey at the time. From “Bottled Honey Shuts Down California Airport” in VOANews:
Two Transportation Security Administration officers were also treated and released from the hospital after being exposed to what were described as “fumes” from the bottles.
