On May 5, 2026, a US Boeing KC-135 Stratotanker aircraft issued a '7700' distress signal while flying over the Persian Gulf, indicating a serious in-flight emergency. The aircraft, which had taken off from Al Dhafra Air Base in the UAE, was conducting refueling operations when it lost its transponder signal over Qatar. The exact cause of the emergency remains unconfirmed, with possibilities including mechanical failure or external threats. Following the signal loss, military helicopters were observed in the area, but there have been no reports of debris or rescue operations.
