Question: What building was increased by 200 feet to accommodate dirigible docking?
Answer: In 1929, Alfred E. Smith, the leader of a group of investors erecting the Empire State Building, announced that the height of the building would be increased by 200 feet so that a mooring mast for dirigibles could be installed. Smith noted that passengers would exit the airship down a gangplank, and a mere seven minutes later could be on the street, ready to experience everything Manhattan had to offer.
