Two news items have highlighted how easily our transport systems can be stopped. In the U.K. a drone has closed the Gatwick Airport, the second-biggest one, and in Melbourne, Australia, the city train loop has been closed down because someone has entered the tunnel on foot. This combined with bad driving and bad weather show how fragile our transport systems are, and with the usual Christmas travel it's going to get even worse.
The real danger is that although these are minor "attacks," a more determined person or group could easily disrupt the transport of food across a country – and it wouldn't take long for food to run out. Our politicians need to look at ways of making the transport system more efficient and reliable, not just bigger. There also needs to be more maintenance, security and even greater punishments for damages.
Keep the roads and airways open, or Santa won't be able to deliver coal to most politicians' stockings.
