Phifty Phantastic Years
Start off trying to build an attack airplane. Change the mission to air defense. Change the engines. Demand a bigger radar. Hit all kinds of stability nasties in the wind tunnel and drastically change the shape to fix them. Pick the airplane for production, rather than another aircraft that's less expensive and has a greater range.
It doesn't sound like a recipe for a classic, but it worked in the case of the McDonnell F4H-1 Phantom II, which made its first flight 50 years ago yesterday (May 27, 1958).
The jet did start off as a grown-up, twin-engine development of the F3H Demon, an ill-starred and mediocre aircraft of the 1950s, and was originally designated AH-1 (A for attack) when it was ordered in 1954. In the following year the mission was changed to air defense and the aircraft was redesigned around the new General Electric J79 engine. The bigger radar was adopted in August 1957 - it gave the fighter its characteristic droop-nosed profile, although the first few aircraft had the original smaller nose and a flat-topped cockpit.

Stability problems were solved by drooping the horizontal stabilizers by 23 degrees, bending the wingtips up by 12 degrees and installing an aileron-rudder interconnect system. The air inlets incorporated shovel-like variable ramps and the jetpipes were cut off under the tail, which was protected from the heat of the exhaust by metal shingles. The great Bill Gunston recalls the staff of Flight magazine in London chuckling over the first pictures: "They must have got everything wrong and tried to fix it", was the general conclusion.

Phantastic plane indeed.
True legend of the skies.

designed and built when they believed that `BVR` was the way forward for aircraft and there wouldn`t be anymore dogfights , using the state of the art Sparrow missiles and sidewinders ..... and when in vietnam it got into twisiting fights they had to train the pilots how to dogfight and bolt a gun to it....

oh how much that sounds like today

UK Phantoms used RR spey turbofans which whilst heavier and slower top end than the US version was actually quicker sub sonic and low down
