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.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever. Your jet fighter pilot experience is available in Melbourne, Cairns and Townsville. Visit flyingwarbirds.com.au for more details.

Modern man’s diet has changed a lot. We have gone astray from the natural ways, and our eating habits have become chaotic and even self-destructive. People no longer find the time to eat well, let alone care for a balanced  diet. And when we have lunch, dinner or supper, we are incapable of putting our worries and stress away for half an hour and enjoy the meal. This is how vitamin supplements have come to be used extensively.

Since too busy work programs have led to the appearance of irregular eating patterns, people no longer assimilate all the nutrients from food. And in time vitamin and mineral deficiencies become manifest, forcing people to undergo medical tests to identify the cause of the problem. People thus have vitamin supplements prescribed, but these are just temporary solutions to your problem.

Find the right vitamin supplements

There are various types of vitamin supplements available, and they have to be adjusted to the user’s needs. Children and adolescents have more intense intellectual and physical activities and therefore they need special vitamin supplements to support their growth.

Nursing mothers and pregnant women should adminstrate vitamin supplements that support baby growth and milk production. There should be enough folic acid and very little A vitamin in such combinations for women to enjoy good health during and after pregnancy.

People who suffer from chronic disease, overweight or accelerated cellular decay, will need antioxidant vitamin supplements.

Natural and synthetic vitamin supplements

Synthetic vitamins are created in labs, and they are not natural organic extracts. When metabolizing such substances, the body could go through very strenuous processes. Most nutritionists now recommend the use of natural vitamin supplements because the absorption rate and the long term efficiency are really great.

Be cautious!

Not all vitamin supplements make a good choice for your health. Self-administration of vitamins and minerals is problematic. Intolerance and side effects are the most common problems reported for the use of some vitamin supplements.

Always check the list of ingredients, the administration instructions, FDA approval and maximum dosage. Don’t buy discount vitamin supplements on the Internet unless you are convinced they are from reliable sources. It’s better to shop for reputed brand names and check the authenticity of the product you buy.
