The UK could have been targets or as Shermy has been waring us for awhile, Rome and the Vatican could be targets.

Those transpolar flights are big planes with a lot of jet fuel. They could strike anywhere on the Euro Continent, Israel, the UK or the US. Even without fuel, traveling at over 500 mph, with their weight, that would a hell of big projectile with a lot of kinetic energy on impact.

I believe the U.S. Capital Dome was the target of the fourth 9/11 plane, and I think they'd still love to get it. Even a plane with a depleted fuel load would wreak havoc on the dome. But I don't think any of these flights could have gotten anywhere near DC without being intercepted. I think Brit targets (or Vatican) are real possibilities for these flights.
