||79: The long-dormant Mount Vesuvius erupted in Italy, burying the Roman cities of Pompeii and Herculaneum in volcanic ash. An estimated 20,000 people died. When discovered, the sites became astonishing archaeological time capsules. Official excavations began on 6 Apr 1748 of behalf of the Italian king's interest in collecting antiquities. | |||

||1907: the Bréguet-Richet Gyroplane No. 1 made what is generally accepted as the first vertical flight, hovering about 2 feet (0.6 meters) off the ground for one minute, powered by a 45 h.p. engine. It was built by the brothers Louis and Jacques Bréguet with assistance from Professor Charles Richet. It lacked stability, any control system, and it needed four men to steady it while it hovered, so it did not represent a practical helicopter. (Some sources give the date as 29 Sep 1907.) | |||
||1909: Panama Canal: Workers pour the first concrete for the Panama Canal at a lock site at Gatun. Finishing all the locks there took nearly four years. A dam holds back the artificial Gatun Lake to supply water for the locks. The Gatun gate was closed on 27 Jun 1913, allowing Gatun Lake to fill to its planned depth. A few months later, on 26 Sep 1913, the tugboat Gatunmade a trial run through the Gatun Locks. The control panel was not ready for the event, so the locks were operated manually. Everything worked perfectly. The Panama Canal crosses the Isthmus of Panama, joining the Atlantic and Pacific Oceans. Built 1904-14, it is only half the length of the Suez Canal. Unlike the Suez, the Panama Canal uses locks to raise and lower ships. | ||1909: Panama Canal: Workers pour the first concrete for the Panama Canal at a lock site at Gatun.
