They were being guided to their targets by Forward Air Controllers from the US Marine Corps — embedded with British ground units and relying on maps, intelligence and the pilots’ own vision.
At the same time, the convoy of British armoured vehicles — two Scimitars and two Spartans — were moving north to probe enemy lines.
They were inside an area US pilots had been told not to shoot into, and carried orange overhead canvas panels used to identify coalition forces to aircraft. They also displayed thermal reflectors and Union Flags.
Circling at an altitude of 12,000ft, the A-10s spotted Iraqi vehicles 800 yards north, and the British patrol less than three miles west. ERROR ONE came when they asked the Forward Air Controller, call sign Manila Hotel, if friendly forces were around the Iraqi vehicles — not to the west. In ERROR TWO neither pilot gave the precise grid references for the Household Cavalry patrol to double check its identity.
ERROR THREE saw them convince themselves the identification panels were really orange rocket launchers.
In ERROR FOUR POPOV36 decides to attack, saying he is “rolling in” — without permission from the Forward Air Controller. POPOV35 asks for artillery to fire a marker round into the target area to clear up confusion.
But ERROR FIVE came when POPOV36 attacked without waiting for it. In ERROR SIX POPOV36 strafes the column for a second time but still doubts its identity.
Only the bravery of Trooper Chris Finney, 18, stopped further attacks. He jumped on a burning vehicle to radio in a Mayday report and call off the strike, dragged a badly wounded comrade from the inferno, then went back in for L/Cpl Hull. He was injured and won the George Cross.
POPOV36 is known to be a lieutenant colonel, and POPOV35 a major, but their identities have never been released. Neither has the result of a US Air Force inquiry.
Last night a senior US military source told The Sun: “This tape needs to get out. The pilots need to be brought to account.”
