British astronaut Tim Peake opened Futures Day at the Farnborough Air Show on Friday.
More than 7,000 children attended the event, which aims to inspire youngsters to study STEM subjects - science, technology, engineering and mathematics.
It was not his first visit to the Farnborough Air Show for Major Peake though, who trained in the Army at the Royal Military Academy in Sandhurst, as he also appeared at Futures Day two years ago.
Speaking to the media ahead opening the event, he said: “I’m absolutely delighted to be back here at Farnborough 2016.
"I was here two years ago on Futures Day as well, which I consider to be the most important day of the air show as it’s all about investing in our future.
“Of course in a young generation and a new generation of engineers, without whom the new challenges we face will be impossible to overcome.
“It still seems fairly surreal that less than four weeks ago I was on board the international space station travelling at 25 times the speed of sound and looking down on planet Earth.”
Major Peake also held a Q&A session with the children, whose questions ranged from asking him about the food he ate in space to whether he was scared when his shuttle re-entered the earth’s atmosphere.
He praised his army training at Sandhurst, which he said gave him the operational skills needed for operating "complex machinery".
But he also spoke of the importance of "soft skills" he learned at the famous academy, which taught him about "communication and working together in a team".
"I owe a huge debt of gratitude to my military career because it formed me in so many ways right from attending the Royal Military Academy in Sandhurst at the age of 19, all the way through to being a qualified test pilot towards the end of my career," said Maj Peake.
“You gain so many skills being in the military, not just operational skills in terms of operating complex machinery but also soft skills such as communication and working together in a team.
“These soft skills are just as important in the space business as your operational skills so really I’ve always drawn on my military training as a foundation as how I can build on being a better astronaut and a better crew member on board the station.”
