Tomasz Nowack, via Flickr A Flickr user snapped and posted this shot of police in front of Heathrow airport today.

This morning, as headlines about the foiled UK terrorist plot blare, you can find on weblogs and media-sharing sites reports filed live from airports via cell phones, pagers, and laptops.

Over at MSNBC, News Producer Clare Duffy filed this account of her experience at JFK International Airport in New York. The report is preceded with this editor's note:

"Clare was on her way to Burbank, Calif., from New York Thursday morning for a Nightly News assignment in Los Angeles. She writes this missive about her airport experience from her Blackberry Wireless Handheld."

I must say, it's a surprisingly lengthy and well-written story for punching it in by thumb on a BlackBerry. Good job!

Other reports from: Tomasz Nowack (at Heathrow airport, via Flickr), BBC user-contributed photos, Kasia (Warsaw, Poland, via MySpace), and Jason Levine (Boston, reporting what his brother-in-law told him while sitting in a Heathrow terminal).

Take-away lesson for professional and citizen journalists: Set up and test your remote posting system in advance.

That is, configure your blogging/photo-sharing tool or content management system to accept or publish postings directly filed from your mobile device. For instance, ShoZu and Lifeblog offer tools for posting to Flickr from certain popular cell phones, and you can upload directly to Flickr by e-mail (free Flickr or Yahoo login required).

Or, if you plan to contribute photos to a news organization's site, look in advance for information on how to contribute. Is there a phone number or e-mail address? Program it into you mobile device.

Also, practice using your system -- and your fallback strategies (i.e., sending content to an editor, friend, or fellow blogger). Creating on-the-spot coverage won't do any good if you don't know how to file or publish it immediately from where you are.

What more could news organizations be doing to prepare systems to leverage the best on-the-spot moblogging/citizen journalism coverage during breaking news? For instance, what might news organizations make from building blocks like Flickr's open API? Please comment below.
