....many hundreds of years, in fact, people fantasised about the ability to fly. That, our ancestors concluded, would surely alter everything. It's now 228 years since the first hot air balloon carried humans aloft. Has this amazing invention allowed us to conquer war, end famine or eradicate cruelty? It has just allowed more of us to travel further and made a worrying contribution to climate change!
We have to be careful when we aspire to progress. We may well get it - but we can't be sure it will do for us all that we hoped it would.
