Boing 747 wingspan and the wright brothers


The Boeing 747 truly represents the current peak of passenger aircraft development. At 150 feet, the 747's economy section alone is longer than the Wright Brothers' first flight at Kitty Hawk. It is the largest passenger jet currently in service, seating up to 524 people. With a width of over 19 feet, the 747 appears from inside the cabin to be enclosed by nearly vertical fuselage walls. The plane can stay aloft for 17-hour flights, storing fuel in the tail structure as well as in the wings and fuselage. With a range of 8,430 statute miles, the 747 can easily connect such far-flung cities as Los Angeles-to-Hong Kong, San Francisco-to-Sydney and Singapore-to-London.

Chocolate and Dogs


While the pathetic begging look that goes across the face of a dog wanting chocolate can weaken the most stoic dog owner, stay firm. Do not give in. Ever.Once dogs have tasted chocolate, they want more.And for dogs, that's a bad thing. You might disagree, thinking back to a time when you noticed a dog enjoying a tidbit of chocolate with no deleterious effect. Don't be fooled.

The problem, according to veterinary experts, is that eating a speck of chocolate leads a dog to crave more. It can mean that your dog will jump at a opportunity to get any type of chocolate, not knowing that certain chocolates are more lethal than other types. Larger amounts of chocolate, particularly of the most toxic type, can bring about epileptic seizures in some dogs, and in all dogs, can kill.

Chocolate contains theobromine. A naturally occurring stimulant found in the cocoa bean, theobromine increases urination and affects the central nervous system as well as heart muscle. While amounts vary by type of chocolate, it's the theobromine that is poisonous to dogs.

You can recognize that your dog has eaten a toxic dose of chocolate from the symptoms. Within the first few hours, the evidence includes vomiting, diarrhea or hyperactivity. As time passes and there's increased absorption of the toxic substance, you'll see an increase in the dog's heart rate, which can cause arrhythmia, restlessness, hyperactivity, muscle twitching, increased urination or excessive panting.

This can lead to hyperthermia, muscle tremors, seizures, coma and even death.

Wrong babies?


It is has been reported by different studies that 100,000 to 500,000 newborns are accidentally switched at birth every year -- and given to wrong parents! According to the 1998 Edition of the Tanderberg Report, (an annual medical study by sociologist Dr. Morton Tanderberg, and as reported by Ann Victoria in Weekly World News, p. 22, on 9-8-98), 500,000 or 1 out of every 8 babies born in American hospitals is sent home with the wrong parents. In many cases, these oversights are caught and corrected within a few days and the babies are returned to their mothers. But on the other end of the scale, Dr. Tanderberg says that in some overcrowded facilities, particularly in large metropolitan areas like New York, Los Angeles and Chicago, the number of switched babies could be considerably higher -- possibly as high as 3 out of 8.

This is weired because it is happening in USA, you would think something like this happens in Africa.
