UK Officials Thwart Potential Terror Plot. From that story:
Congestion was building up rapidly at the airport as authorities enforced strict new regulations banning most hand baggage.
British Airways said some flights were likely to be canceled. Laptop computers, mobile phones, iPods, and remote controls were among items banned from being carried on its planes.
Fox News TV was also reporting the additional security measures banned ALL cary-ons. This would include things like books, all liquids (water, baby formula, etc….), among other things.
I'll post more later (maybe this evening).
