"Five years on
what false alarm can be trusted again?
What case or bag can be left unclaimed?
What flight can be sure to steer its course?
What building can claim to own its form?
What column can vow to stand up straight?
What floor can agree to bear its weight?
What tower can vouch to retain its height?
What peace can be said to be water-tight?
What truth can be said to be bullet-proof?
Can anything swear to be built to last?
Can anything pledge to be hard and fast?
What system can promise to stay in place?
What structure can promise to hold its shape?
What future can promise to keep the faith?
Everything changed. Nothing is safe."
- An extract from 'Out of the Blue' by Simon Armitage, written to commemorate the September 11th attacks five years on.
