Have just read an interesting little factoid from 2006. Remeber the transatlantic liquid bomb plot? Well apparently, on the day that John Reid made a statement about it (August 10th), he was accompanied by the hten Transport Secretary "wee" Dougie Alexander.
Alexander didn't really say much, but was there thanks to his use of the Queen's Flight (also known as 32 Squadron) by helicopter. That flight only cost the taxpayer £13,895.55. Had he used a scheduled flight (and enjoyed the chaos other travellers were facing) it would have been a mere couple of hundred, a train would have been as effective too.
