“SEP 28, 1960: The CIA attempts its first drop of weapons and supplies to the Cuban resistance. The aircrew tries to drop an arms pack for a hundred men to an agent waiting on the ground. They miss the drop zone by seven miles and land the weapons on top of a dam where they are picked up by Castro’s forces. The agent is caught and shot. The plane gets lost on the way to Guatemala and lands in Mexico.”
