extracted text (Extract Text): BOMBS of low explosive force,
made of terra cotta, and loaded
with black powder and shotgun
ammunition, have recently been
brought into service at Rockwell
Aviation Field, San Diego, Cal. for
training United States military avia-
tors.
These practice bombs
have little destructive force.
They are loaded with just
enough explosive to burst
upon striking the ground,
producing a dense column |
of smoke that enables avia- |
tors flying as high as 20,000
feet to observetheir contact. |
