For the first time ever, the Thunderbirds and U.S. Navy Blue Angels debut a flight formation known as the “Super Delta” during a joint training evolution on March 2, over the Imperial Valley.
After the 2020 very successful joint flyovers during “Operation America Strong”, both US Demonstration Squadrons will continue this incredible joint formation flying in 2021 at National Memorial Day Parade: America Stands Tall in Washington, D.C.
