   EVENTS LAST MONTH (21):

 
   
Edmonton Tornado - July 31 @ 01:00
On this day in 1987, a large tornado ripped through Edmonton, killing 27 and causing a third of a billion dollars in damage.
   
Aphelion - July 6 @ 13:30
Earth is farthest from the Sun in its slightly elliptical orbit.
   
Full Moon - July 29 @ 10:35

Post=Tropical Storm Blanche - July 28 @ 01:00
A powerful post-tropical storm when it made landfall in Nova Scotia in 1975, this system dropped heavy rainfall over much of the province, accompanied by high winds and considerable thunder. The Author experienced this storm first-hand, on Sober Island, NS.
   
World War I Begins - July 28 @ 01:00
The global conflagration popularly called the "Great War" during the period, was the first war involving major powers worldwide. On this day, in 1914, a Serbian Nationalist assassinated Archuduke Franz Ferdinand, the heir to the Austro-Hungarian crown. Austria-Hungary declared war on Serbia the same day, and within weeks most of the global powers were pulled in, eventually including the United States. Over 17-million (17,000,000) people lost their lives in the conflict, including some 65,000 Canadians. The war ended in 1918, now 112 years ago.
   
Amelia Earhart born - July 24 @ 01:00
On this day in 1897 (129 years ago), pilot Amelia Earhart was born, in Atchison, Kansas. A trailblazer for later generations of female pilots, she eventually lost her life after crashing on or near Howland Island, in the Pacific Ocean, on one of the later (and most-dangerous) legs of a round-the-world expedition. There is plenty of evidence that she survived the crash; shortwave radio calls, for example, which were triangulated to Howland. The search for the plane's wreckage is ongoing.
   
Comet Hale-Bopp discovered - July 23 @ 01:00

Apollo 11 Landed - July 19 @ 01:00
On this day in 1969, the Apollo 11 Moon mission landed on its target while the world held its breath. Two American men--Neil Armstrong, and Edwin "Buzz" Aldrin--walked on the Moon early the next day.
   
Impact Day - July 16 @ 01:00

HMCS Bonvaventure decommissioned - July 3 @ 01:00
On this day in 1970, HMCS Bonaventure was decomissioned after 13 years' service. This vessel was Canada's third aircraft carrier, after Warrior and Magnificent. Some 215 metres long and 34 wide, she was a small (by modern standards) ship of her type, but she was able to maintain a constant aerial screen during operations. Originally laid down during WWII, as the British ship HMS Powerful, she was mothballed after the war; she was acquired by the Canadian government in 1952 and commissioned in January of 1957. The Author nostalgically remembers car rides past her, in the Halifax dockyard, in the late Nineteen-Sixties. She was a big ship.
   
Battle of Beaument-Hamel - July 1 @ 01:00
July First has a different meaning for Newfoundlanders, who observe the anniversary of this battle, which occurred during the opening of the Battle of the Somme, in 1916. The Newfoundland Regiment suffered heavy losses that day; but they, like their Canadian brothers, emerged from this baptism of fire with a hard-earned reputation as front-line troops. After the war, a stunning monument was erected at the site, featuring a bronze caribou on a large stone pedestal.
   
Battle of the Somme - July 1 @ 01:00
From this day in 1916, to November 18, Canadians were engaged in the Battle of the Somme. The battle helped to cement their reputation as hardened, first-class troops who gave their all in the quest for victory.
