CNN posted in their headline via their mobile RSS feed that aboard the delayed flight to Michigan a passenger set off fireworks, delaying the 330 airbus from its designated arrival. Fireworks remain depicted within the story yet according to their current headline, updated at 7:04 pm, the fireworks are now specified as an explosive device.
An explosive device by definition is not a firework. Thanks CNN for using fear enhancing terminology to buff your ratings. You're closer to FOX than I thought.
