TopGear runs Heathrow

I've lost a Jumbo Jet in my blind spot. About 350 tonnes of roaring aeroplane has disappeared somewhere over my right shoulder, leaving nothing but a wing tip in the corner of my eye. I've occasionally lost scooters back there. The odd hatchback has gone missing. But a fully fuelled 747, travelling at 250kph down the middle of the runway at Britain's biggest airport? You might think this sounds impossible. But when you're driving around one of the world's busiest airfields full of buses, tugs and catering lorries, one of the hardest things to see is, in fact, an aeroplane.
