Four years on

So I work in organisational communication, but my passion is air and space history. And today is another of those sad commemorative days, remembering the crew and families of the Shuttle Columbia. No doubt there'll be coverage today on NASA's site, and I hope the emphasis is on the lessons learned and our quest, as a race, to broaden our horizons in space.

We're too often held back by political expediency, but surely it's only human to reach for the stars?
