First nuclear aircraft
carrier
 In 1960, the first nuclear-powered aircraft carrier, the USS Enterprise, was launched in Newport,
Virginia. It was the most astonishing vessel of its time and by far the largest warship in the world. Powered by eight nuclear reactors, it does not need to carry
its own fuel oil and so has more room foor aviation fuel and weapons. In 1963, Enterprise and two similarly powered cruisers
made a non-stop voyage around the world to demonstrate the viability of nuclear power. Length: 1120 ft, flight deck width:
250 ft, displacement: 93,970 tons. Speed: 33 knots. Range: 470,000 miles at 20 knots.Air wing: 86 aircraft. Crew: 5765
Traffic signal
In 1909, Thomas M. Flaherty filed for a U.S. patent, with an idea for a "Signal for Crossings" This was the first
U.S. application for a traffic signal design, later issued as No. 991,964 on 9 May 1911. His signal used a large horizontal
arrow pivoted on a post, which turned to indicate the right of way direction.
