Hiding alone in a mountain crevice behind enemy lines, the injured American airman knew exactly what to do: survive and evade.

US special forces carried out a daring rescue mission to bring back an airman stranded behind enemy lines after Iran shot down a $31 million fighter jet on Friday. Donald Trump said on Sunday that dozens of military aircraft had raced to rescue the missing weapons-system officer of an F-15E after the pilot ejected and was rescued under fire.

The search for an American crew member missing behind enemy lines in a rural stretch of Iran continued Saturday as armed Bakhtiari tribesman tribesmen have fanned out across the desert terrain in a bid to find the vanished US military member.

“This brave warrior was behind enemy lines in the treacherous mountains of Iran, being hunted down by our enemies, who were getting closer and closer by the hour,” said Mr Trump, adding that the colonel “sustained injuries, but he will be just fine”.

For pilots, the most dangerous part of the mission often begins after they eject, according to a retired brigadier general.

The fighter jet was the first American aircraft to have crashed in Iranian territory since the U.S. and Israel launched the war, striking Iran on Feb. 28.

U.S. President Donald Trump on Sunday made expletive-filled threats against Iran and its infrastructure if it doesn't open the Strait of Hormuz by his Tuesday deadline, after American forces rescued a wounded aviator whose Iran-downed plane fell behind enemy lines.
