As the media, including the BBC , Aljazeera and news.com.au report, air travel to and from UK airports has been disrupted by what the BBC describes as an "airlines terror plot".
A common thread of all reports, supported by references to and pictures of chaos at Heathrow, is that intending travellers should defer travel if possible or otherwise be prepared for long delays and extra security precautions, including restrictions on cabin baggage (which seem to extend to personal reading matter).
As I seek more information on the subject, the advertisers who fasten on to my searches seem oddly inappropriate, to say the least. Here are some example of "sponsored links" (sponsored not by me needless to say):
