Although the 94-year-old broadcaster and naturalist has spent almost 70 years flying around the world to create nature documentaries, he admitted he now hates planes and can't see himself going abroad by air again.

David was asked by Radio Times if he plans to travel overseas for filming again and he replied: "No, not a lot. It's probably a fact of age, but I was finding my heart was sinking deeper and deeper into my boots every time I walked up into an aircraft and looked down that long line and thought, 'I'm going to be here for another 24 hours'. It didn't make my heart lift with pleasure."

Meanwhile, David has been vocal about the dangers of climate change and said he believes air travel should be more expensive in order to protect the environment.

He previously explained: "I think that one way to reduce these things is to count the costs of what it is that air travel costs in real terms — in what it costs the environment. And if you cost that, then you will see the tickets are extraordinarily cheap."
