The sky is really like a big ocean above us and aircraft control surfaces in many ways mimic boats at sea, with rudders and trim. But is that ocean above us getting choppier, and if so, why? Following two high profile incidents in recent weeks, clear air turbulence is a suspect in the heavy jet liners being thrown around. The question now is whether climate change is having an impact on aviation, as well as how much impact aviation itself is having on climate change.

It speaks to the enduring fascination with flying machines and exhilaration that thousands upon thousands attend air shows across the globe, and one of the biggest in Europe is about to return on our very own doorsteps with the Bray Air Show resuming normal service this Sunday in the Co Wicklow seaside town. I was lucky to play the tiniest of roles in its preparation today.
