Gantenbrink's Robot Discovers Copper Fittings in Shafts
Detailed Account
German engineer Rudolf Gantenbrink sends a robot (UPUAUT 2) up the Queen's Chamber southern shaft and discovers a small limestone 'door' with two copper fittings — pins or handles. The shaft was sealed at both ends and had never been opened. Copper is a conductor and resists hydrochloric acid corrosion. Combined with chemical residues (zinc chloride, HCl) found in the shafts, this suggests a functional purpose far beyond 'ventilation' or symbolic 'soul passages.'
