 On 7 September 1909 two visitors were left stranded at the top of the tower as the final lift car of the night descended without them . The woman and twelve @-@ year @-@ old child were not noticed during the final round of inspection and so , without a way to communicate with anyone on the ground , they spent the night on the tower until 10 am the following morning . They did not appear too concerned by the ordeal and left without giving their names to officials .
