ATOMIC CAPE CANAVERAL - record included

The Giant Battle of the Blue & Grey had a record included with its set, as did the Marx Atomic Cape Canaveral.

Here's from a posting on a Remco (other toy & playset maker) forum:
"A record included with Marx's Atomic Cape Canaveral sets the mood with a narrator reading instructions for Junior Missile Officers. Eventually, he announces "This is a live launch. All unauthorized personnel will now leave the ready room and lift-off area." In the background at Central Control actual technicians can be heard "Roger Wilco-ing" each other amid beeps and effects. This is followed by a countdown, blastoff, and tracking officer who states "The missile is on course. The satellite is in orbit." If all that doesn't get you ready to spring off a dozen rockets and saucers, you must be from another planet!"
