The delay by the Allied Enemy was just what Supreme Commander Gordon wanted. It gave him time to prepare. He had ordered the Henry Motor Company of Detroit to proceed at once to manufacture according to his plans which he sent them, two large machines, one positive and one negative, by which he could send currents of electricity thru the air and produce a vacuum, or as he called it, a "Tunnel thru the Air." These plans had been worked out years before and there was no question but what the machines would work successfully. The Henry Motor Company had been commandeered by the United States Government and as soon as they received the order and plans from the Supreme Commander, they started running day and night working to build the two giant machines. The fifteen days' armistice expired on October 18th, 1931. Supreme Commander Gordon was in readiness and waited the first attack of the enemy. Less than thirty days from the time that he ordered work started on the machines, they reported that the machines were completed and ready to test out. He called Colonel Kennelworth to his office in New York and explained to him that the great Vacuum Producer, as the machine had been named, had been completed; ordered him to proceed at once to Detroit and test out the machines both for short and long distance work. Colonel Kennelworth arrived in Detroit on November 17th. The following day tested out the Tunnel machines; reported to Supreme Commander Gordon that they were working in fine shape and producing results according to the plans. The Supreme Commander then decided to go immediately to Detroit and establish one of the machines at a base there and have Colonel Kennelworth take the other machine to Cincinnati and set it up. The machine was transported secretly and successfully to Cincinnati and set up in one of the largest buildings in the city. On November 20th, Supreme Commander Gordon and Colonel Kennelworth tested the Tunnel machines over this long distance. The machines were set to produce a tunnel 100 yards wide at first and were set in motion. The American scouting airplanes were sent off over a described area and on entering between these lines found that they were in a complete tunnel. They could travel quickly back and forth thru the Tunnel in the Air. This was a great triumph. Commander Gordon instructed all those connected with the test to keep it a complete secret. He knew that this was going to be a great surprise to the enemy when they started their next attack. Supreme Commander Gordon had now completed another new invention on the same plan of the radio that he had to use in his office in New York several years before to record conversations when the manipulators were trying to catch him in the stock market. He had enlarged this machine so that it would record voices 3000 miles away and named it the "Tel-Talk."
