In reply to The Lemming:
you can hope he has inspired a few people, even just 10% of kids to take an interest in science, but that really depends how much he does once back on earth, visiting schools. Granted most kids who do maths and science won't be astronauts, but in their life time space travel is likely to change dramatically and given the UK has a fairly decent space industry, it should try and remain ahead of it's competitors in some sectors.
A televised landing in all schools would have helped, but landing on a Saturday is pretty inconsiderate of them.
