January 21, 1976 - Heathrow Airport for Bahrain in the Persian Gulf
The commercial supersonic passenger service began with two simultaneous Concorde jet airplane flights. One left London's Heathrow Airport for Bahrain in the Persian Gulf. The other flew from Orly Airport outside Paris to Rio de Janeiro via Senegal in West Africa. With engines twice as powerful as those of normal jets, their 1,350 mph cruising speed was double the speed of sound (Mach 2.04), and halved air travel time, at a cruise altitude of 60,000 feet (17,700 m). Their huge production cost was shared between Britain and France governments. Technical challenges included building the aircraft's frame to withstand immense pressure of shock waves and endure high temperatures from air friction. The Concorde had a delta wing configuration, and was the first civil airliner to be equipped with an analogue fly-by-wire flight control system. Regular transatlantic flights from Europe began in Washington, D.C. on 24 May 1976 and service to New York on 22 Nov 1977. The final commercial Concorde flight was on 24 Oct 2003.
January 21, 1970 - From New York's John F. Kennedy Airport and Heathrow Airport in London, England
The first wide body jet was put into service as the Pan American Airways Boeing 747 flew its first flight between from New York's John F. Kennedy Airport and Heathrow Airport in London, England. This "jumbo jet" had a cabin almost twice as wide as a 707 and a length of 231 feet. The cockpit and first-class section were above the first floor of the passengers. With the ability to carry more than 400 passengers more than 5,500 miles, the 747 opened up economic long-distance travel to the masses.
Until a man duplicates a blade of grass

"...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

"...The Revolution was effected before the War commenced. The Revolution was in the minds and hearts of the people; a change in their religious sentiments of their duties and obligations. This radical change in the principles, opinions, sentiments, and affections of the people, was the real American Revolution...."

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.
