The recent events in Iceland have me thinking. I regularly feel sorry for the poor sods huddled out in the rain having a fag (in the British sense). Society hates them. I'm sure they hate each other. And themselves. Now, we can put all that hatred into defending our airports from the dreaded (and largely mythical) Al Qaeda. I noted - with mounting excitement - that the RAF was suspending its flights around the UK with its much-vaunted Typhoon fighter until the volcanic ash has settled. Ash. Ash? Ash! The penny dropped.
At each airport in the country I would build strategically located smoking areas atop huge fans. The ashtrays would never be emptied in these areas, allowing for a good build-up of ash and butts (in the British sense) within days. At the merest whiff of Nasty Al attacking we would turn the fans on. Ash et al as far as the ionosphere! Admittedly my "Strategic Ash Initiative" would paralyse air transport across the globe but - hey - the smokers would feel good about themselves and everyone would smell like they do.
