Raid Balloon Alarms and Chungking, Mar. 15.
Coloured balloons will be used as air-raid signals in the event of failure of the usual sirens, it is announced here today.
When a Japanese air raid is likely, or if raiders are at a flying distance of approximately one hour and 20 minutes from Chungking, one red balloon will go up.
The "rst alarm," meaning "Japanese bombers are approaching Chungking," will be indicated by two red balloons. The " alarm" wilt be signalled by lowering both balloons, while the "all clear" wil be indicated by using a green balloon.—Reuter.
