DESCRIPTION: |
|
The marker consists of a fragile, paper-sided body of square cross section, fitted with wooden end pieces and filled with aluminum powder. The outside is coated with aluminum paint. The body is surrounded by a loose cardboard sheath to protect it from damage while being handled. |
|
FUNCTION: |
|
When the sea marker is dropped from a plane, the sheath separates from the mar-ker, and the latter bursts in impact with the sea, leaving a patch of aluminum powder floating on the surface. |
