The Royal Air Force paid tribute to the NHS and key workers by creating a blue heart in the sky during their training session in Lincolnshire.
The Red Arrows aerobatic team said they wanted to "show appreciation for the NHS and our key workers" with a blue heart in Scampton.

"The amazing blue heart, both during and after it was painted over the Scampton skies by the Red Arrows Synchro pair," wrote a RAF photography page on Twitter.
"Recognition to the NHS and key-workers across the UK, working tirelessly throughout this pandemic."
It came as Prime Minister Boris Johnson and Carrie Symonds led the nation in its weekly tribute to the thousands of NHS staff and healthcare workers putting their lives at risk in the fight against coronavirus.
