The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.
Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.
Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.
But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).
During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.
North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.
The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields resulted in~yielded~produced an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.
Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.
Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful trend~wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.
New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.
Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

Directory Submission Tips
So you’ve decided to market your website? Well in this article we are going to discuss one of the easiest, most effective, and cheapest ways to do this. Directory submission is basically the act of submitting a website to a web directory, but before we get into how to do this properly we need to understand exactly what a web directory is.
Web directories are web sites that provide searchers with links to websites they are looking for. Web directories are totally different than search engines; with a search engine websites are listed by a computer based upon keywords that are contained within specific pages, but with a web directory websites are usually handpicked by a human and listed by category and subcategories.
When submitting your website for consideration into a web directory you are going to want to make sure the quality of your work is second to none. Stuffing your web pages with keywords and links is not going to help you in the least bit, if you do this you have very little chance of getting your website listed in any high pagerank directories.
The best thing to do is choose quality over quantity. The second thing you should do is submit your website to as many directories as possible, even the small ones. It is great to get your website listed in a high pagerank directory like google or yahoo, but if you get your page listed in a bunch of small ones you will also see great results.
One of the more controversial things you can do is use the service of a directory submitter. This person will either manually submit your website to directories or use submission software to spam out the directories until they accept your website.
If you feel that this is the way you would like to go try it; but I do not recommend this method because each directory is different and has a different set of requirements for admission. In addition if your website gets declined it will be considerably harder to get accepted when you submit your website again, so it is best to get it right on your first try. Manual directory submission is the best way to go.
Lastly make sure to write a very truthful and interesting description of your website. Once you have gotten accepted into a directory you want to make sure that your description grabs the attention of searches, in addition listing your homepage first makes more sense than listing one of your other pages because visitors to your website are more likely to go from your home page to other pages than from other pages to your home page.
If you follow these simple rules I am sure you will be very successful in marketing your website. Good Luck!

I smoke 2 packs a day.
I quit cold turkey and boy was it miserable! That was 15 years ago and Ive never looked back. 2 packs a day is really a strong habit. You know there are the gums and patches and nasal sprays that contain nicotine and many people do have luck quitting with these methods. i was thinking, tho, that in your case maybe hypnosis would work.i don’t know if this link is any good but it looked interesting. Good Luck and do it soon!http://www.viahypnosis.com/quitsmoking.htm
I would like to get answer from the persons who have quit smoking for more than 2-3 months,
Please share your experiences.
i have beter health at all.
i have beter body odour than before.
i can have more frequent sex than be 4
i have more fresh lung to inspirate air. Now i can have more miles for my aerobics exercise. the conclusions not smoking is beter than smoking.
I had an addiction to smoking. My therapist said that a beautiful woman like me should not be smoking under any circumstance. then i quit and now im getting more sleep then ever why?
I don’t really have an answer but I can tell you you’re not alone. I have been smoking for 6 years and i have quit twice and when I do I get much more sleep. I think it may have been the withdraws. But I did hear that smoking has a tendency to keep you awake more if you smoke at night. Don’t know if it’s true or not but when I do have a cigarette before heading to bed I am a bit restless for a while.
