Military jets flew over US cities to salute frontline workers in the country with the highest coronavirus caseload and death toll in the world.
The Thunderbirds hailed health workers and first responders battling the novel coronavirus, which has infected more than 1.1 million in the US and killed more than 66,000.
"They are an inspiration for the entire country during these challenging times and it was an honour to fly for them today," the group said.
