Thankfully, this was a FAILED attempt to blow up a plane. Having flown from Amsterdam a few times (with plans to do it again in the future), this is especially terrifying to me. Also, it looks like the passengers sprung into action and subdued the would be murderer. But, this is the scariest part of it:

The man was apparently already on the government’s no-fly list of suspected terrorists, ABC News said a senior intelligence official told them.

Not good. Either Delta failed to deal with someone on a no-fly list or the Amsterdam authorities failed. That’s scary all the way around.
