A passenger boarded a plane in Boston and was in Miami to catch a connecting flight to Jamaica.
While he was on the plane, his luggage was being loaded on the plane. A baggage handler slammed his bag on the tarmac.
The contents of the bag, hundreds of pistol primers, ignited.
The 37 year old passenger was promptly hauled to the pokey, where he faces charges of transporting hazardous material.
No one is saying how the pistol primers made it on the plane back in Boston but they assure us "there is no terrorism nexus to this incident," says FBI Miami spokesman Michael Leverock.
So, apparently, hide your toothpaste in pistol primers instead of your shoes and you'll be just fine.
