Two American B-52 bombers, accompanied by several aerial refueling planes and a group of fighter jets, carried out a surprise air sortie over the Middle East yesterday morning. The flight departed from Britain, passed through the airspace of Jordan and Iraq, and then crossed the Arabian Gulf near the Iranian coast.

During the flight, the bombers were prevented from entering Egyptian airspace because no advance notice was given to the competent authorities, according to a recording of the pilots' conversations.

The ban on the bombers from entering Egyptian airspace comes at a sensitive time amid rising tensions between Egypt and Israel. 

These tensions may have influenced the decision not to allow the aircraft to fly over Egyptian airspace. Given the current political situation in the region, Egypt may take strict security measures to ensure the protection of its airspace, especially in light of the political and military developments in the Middle East.

The military actions of both sides increase the state of security alert in the region, while emphasizing the importance of coordinating air operations with neighboring countries to ensure security stability, which may be one of the factors that motivated the Egyptian authorities to prevent the American bombers from crossing Egyptian airspace.
