Terror Attack?

Good day from New York, where we are carefully following today's frightening incident at the Glasgow International Airport in Scotland.  We all know what immediately comes to mind when we hear a car has plowed into an airport terminal bursting into flames, especially a day after those two car bombs were diffused in London. The witness accounts all suggest it was a deliberate act, but at this writing, whether it is an act of international terror related to the London car bombs remains to be seen.

A year ago I was in the UK covering a terror threat to US-bound airliners from London.  That incident is the reason these days we are forced to carry our shampoo and contact solution in ziplock bags to get through airport screening checkpoints.  Before that, it was a shoe-bombing attempt aboard a London to Miami flight that resulted in us having to remove our shoes before we enter the concourse. Within hours of today's incident in Scotland, American airports were again ramping-up security, and I can't help wonder if the days of getting dropped-off at the terminal door are now numbered. Is that what we will remember this day for?

NBC News senior investigative correspondent Lisa Meyers will join us from the UK to lead our Nightly News coverage tonight of the Scottish airport incident and what investigators have learned about the London car bombers.

We are also covering the flooding situation in Texas and Oklahoma.  Our Jay Gray is working that story.

Pete Williams will take a look at the Supreme Court's strong swing to the right, and Mike Taibbi on America's newest big cities, and what the latest census numbers say about the way we live.

Thanks for checking-in. I hope you join us tonight for NBC Nightly News.
