Bonn, Feb. 10: British Beverley troop transport planes are in readiness today at West German air-fields, for further patrols of the air corridors to Berlin, following Soviet attempts to reserve parts of them for their own military transports.

A British spokesman said early today that the four-engined Beverleys, flown from Britain, have already patrolled one of the corridors — from Hamburg to Berlin. The spokesman did not disclose the number of planes, which have been moved from Britain. They have been operating with other allied military planes in the corridor.

In Berlin yesterday, the Western Allies rejected the Soviet attempt to reserve air space in the corridors as “illegal.” In a statement they said that the Soviet Controller at the Berlin Air Safety Centre had requested reservation of all altitudes up to 7,000 feet, in the Berlin-Frankfurt corridor, for Soviet military transports and a similar reservation up to 7,500 feet in the Berlin-Hamburg and Berlin-Hanover corridors.

The three corridors are 20 miles wide, and in past months East German and Soviet authorities have repeatedly alleged, that they were being “misused” by the Western Allies and that “Western militarists and revenge seekers” have been flying along them to Berlin.
