The RAF is investigating a crash involving one of its high-speed Hawk fighter jets after two of its pilots ejected and parachuted out of their plane moments before it crashed and burst into flames.

The RAF said that training on these jets had been "temporarily" paused as a "precautionary measure".

North Wales Police said the pilots, who had been flying a training aircraft, were being treated for minor injuries.

While an investigation is under way, here is what we know so far and what the crash footage shows us, according to one expert.

The Hawk T2 aircraft had been flying out of the RAF Valley base on Anglesey when it plummeted to the ground at nearby Pencarnisiog.

According to BBC Security analyst Mikey Kay, who also served in the RAF for 20 years, the area was "perfectly situated for training pilots" and was part of the "low-flying system".

According to the Ministry of Defence, there are 20 low-flying areas - also known as tactical training areas. They are located in central Wales, northern Scotland, the borders area of southern Scotland and northern England.

RAF Valley is also close to the Machynlleth Loop - a series of valleys between Dolgellau in Gwynedd and Machynlleth in Powys.

The loop, also known as the Mach Loop, is an attraction for aviation enthusiasts and photographers

"These pilots they train in low level, they train in instrument flying, formation flying, general handling, so that area, the Anglesey area and its accessibility to all of those landscapes for the requirement of training is perfect," said Kay.

The jet involved was Hawk T2 - a two-seat training jet by BAe Systems used for advanced jet training, and designed with similar controls to the Typhoon fighter jet.

According to the RAF, it comes with an advanced "glass cockpit", and the aircraft is also used for the "most advanced fast jet training for RAF pilots".

The older version of the T2, Hawk T1, is also used by the Red Arrows, which the BBC understands are also included in the pause. However, they were not due to fly again until Le Touquet Airshow in France this weekend. It is not known when the restriction will be lifted.

Kay, a former RAF pilot who grew up three miles away from RAF Valley, shared video on social media appearing to show flames rising from the rear of the T2 jet, external as it rolls down the runway.

As the jet climbs, the flames seem to disappear. It is not clear how long after take-off the pilot's ejection from the plane took place.
