Flown Apollo 12 “Boost Cover Release” hatch label removed from the crew access hatch of the Command Module Yankee Clipper after the capsule successfully returned to Earth on November 24, 1969. The label, 4.25 x 4.75, reads “Boost Cover Release” and is comprised of two layers: one of Kapton foil with gold side facing downwards, which is topped by a second later bearing the actual label. Presented in a museum-grade acrylic display case with engraved plate and mission patch to an overall size of 6 x 13. In very good to fine condition, with bubbling and burn marks resulting from re-entry into Earth's atmosphere. Accompanied by a comprehensive booklet from The Space Collective detailing the authenticating factors, history, and relevance of the Apollo 12 Command Module primary access ‘Boost Cover Release’ hatch decal, which includes ample photo-matching evidence.
During an Apollo launch, the command module (CM) is enclosed by the boost protective cover (BCP), a multi-layer, resin-impregnated fiberglass assembly designed to protect it against aerodynamic heating during the 'boost' phase of the mission. The BPC has a hatch that covers the CM's crew access hatch. When the CM hatch is opened from the inside, it activates a release mechanism between the crew hatch and the BPC hatch. This mechanism releases the BPC hatch and allows the two hatches to swing open together.
The ‘Boost Cover Release’ decal was used to indicate to the NASA ground crew where to insert their tools to release the boost cover on the primary access hatch in the event of an emergency on the pad. This system would allow the crew to escape the vehicle as soon as possible, a safety precaution designed and built into all command modules after the tragic deaths of the Apollo 1 crew.
