The Red Arrows - the RAF's team of very skilled display pilots - are returning from their latest 60-day world tour.

The tour saw them perform a public display in China for the very first time in their history.

It was their biggest tour abroad in a decade, including visits to other countries including Singapore, Malaysia, Oman, Bahrain, the UAE and Kuwait.

The Red Arrows have now performed in 57 countries since the group was formed in 1965.

But where did they come from and why are they so important?

The Red Arrows form part of the UK's Royal Air Force (RAF), as its aerobatic team.

They are a flying display team that demonstrates to the public all of the skill, ability and speed of RAF pilots.

They fly in impressive shapes and formations, extremely close together, and are known for making smoke come out of the back of their planes to draw patterns in the sky, as you can see in the picture below.

There are nine pilots on the team - two of which were new this year - who are named Red 1, Red 2, Red 3 and so on.

The pilots fly planes called Hawk Jets, which are painted bright red and can reach speeds of just over 600 miles per hour.

The team isn't just made up of the pilots, though.

There are more than 120 people on the Red Arrows team, including engineers and support staff needed to make sure the planes keep working and the team is run successfully.

Its home is RAF Scampton in Lincolnshire.

The Red Arrows were formed in 1964, when the RAF decided to bring together all of its display teams.

"Red Arrows" is a mix of the names of two other teams at the time - the Black Arrows and the Red Pelicans.

In their very first year, the Red Arrows performed 65 shows. By the end of 2015, the team had flown 4,725 displays!

They celebrated their 50th birthday in 2014, with lots of celebrations and special displays.
