Early reports indicate that the pilot of a US F-15 fighter aircraft downed over Iran was rescued - which, if confirmed, would be the latest in the long history of US combat search and rescue missions. The search operation is ongoing deep inside Iran for a second crew member, according to CBS, the BBC's US partner.
Combat search and rescue (CSAR) missions are considered among the most complex, time-sensitive operations that US and allied militaries prepare for. In the US, elite units of the air force are specially trained for CSAR missions and are often pre-emptively deployed near conflict areas where aircraft could be lost.
Put simply, CSAR missions are military operations aimed at finding, aiding and potentially rescuing personnel in need, including downed pilots and isolated troops. In contrast to conventional search-and-rescue efforts - which could take place during humanitarian operations or after disasters - CSAR missions occur in hostile or contested environments.
Verified video that emerged from Iran on Friday appeared to show US military helicopters and at least one refueling aircraft operating over Iran's Khuzestan province. These missions are extremely time-sensitive, as enemy forces would likely be deployed in the same area to try and locate the same US personnel the CSAR teams are trying to rescue.
Iranian officials have urged citizens to locate the missing US crew member alive and are offering rewards for their capture, presenting significant challenges for the ongoing rescue efforts
