The Transportation Security Agency has banned the old Transformer toys from airplanes.
As a commenter writes in the Corner (which provided the link):
It's also significant that Megatron and Shockwave are singled out and banned from airplanes -- "Toy transformer robots (this toy forms a toy gun)". What about the rest of the Decepticons? What about Starscream, who turns into a fighter jet with missles?
We eagerly await clarification from the TSA.
