The Me-163 Komet has the distinction of being the only rocket-powered fighter plane to serve in active duty. As you can imagine, the Komet was fast! It not only beat the world speed record, it doubled it. Flying up to 624 mph, nothing would beat it until Yeager flew the Bell X-1. But the aircraft, designed by Alexander Lippisch for Nazi Germany, had some drawbacks.
The speed monster devoured all of its rocket fuel in just seven minutes. Its weapons system was inaccurate and slow, so slow targets were impossible to hit. And the Me-163 was actually too fast to be a fighter, outflying its intended targets. On top of that, it had no landing gear and was out of fuel by the time it landed; needless to say, it was unsafe. Getting it back in combat was also a mission of sorts. The aircraft was a boon to the future of aeronautic aviation, but it was a failure against the Allied forces.
The HZ-1 “Aerocycle” Heli-vector
Designed to be a personal helicopter, the U.S. Army developed the Aerocycle as an experimental program that would convey soldiers, like a cavalry of massive dragonflies, over the ocean to battles on land. The Aerocycle promised battlefield mobility far exceeding motorcycles or infantry vehicles. It could hit 65 mph and patrol a range of 150 miles. The military hoped that soldiers could be trained on the craft after 20 minutes of practice, but that turned out to be the demise of the machine.
The Aerocycle proved to be unsafe for inexperienced pilots. Two crashes were caused when the spinning rotors struck each other and spun the craft out of control. Windy conditions created another weakness, and the project was ultimately scrapped. If you want to see one, a HZ-1 Aerocycle is on display at the U.S. Army Transportation Museum at Fort Eustis.
The Christmas Bullet
Dr. William W. Christmas, the man who backed the Christmas Bullet airplane, was such a practiced charlatan that he hoodwinked the U.S. military into investing in his aeronautical experiment. During the days of the Wright brothers and the race to fly heavier than airships, something heavier than a hot air balloon, Dr. Christmas was in the running.
Though he had no credentials, in that they did not exist then, he claimed to be an aerospace engineer. He claimed to have built and flown a plane in 1908, but he had no evidence. He said the plans and plane burned in a fire. This turned out to be false. Nevertheless, the con artist found two backers from an aircraft company in N.Y. and managed to procure an engine from the U.S. Army. Christmas built his plane to his design specs, in spite of warnings from the company’s engineer. He should have listened. The wings were ripped off the fuselage on its first test flight, killing the pilot. Undeterred, Christmas advertised in Flying magazine that his plane flew at a top speed of 197 mph, failing to mention the crash was caused by his design flaw. He was able to build another Christmas Bullet which faced the exact same fate. It’s known as the worst airplane ever made in U.S. military history.
The Noviplano Ca.60
After the Great War and its feats of engineering in military technology, great optimism arose. Entrepreneurs and aviation companies raced to bring the next new dream to the public, while militaries worked diligently making faster and deadlier machines in time for WWII.
In 1921, designer Gianni Caproni built a giant transatlantic flying boat. He hoped to fly 100 people across the Atlantic at 100 mph in his sea-to-air contraption. It had eight engines and three sets of wings. His hydroplane flew, but it crashed into pieces. His project, relegated to the annals of history, is mostly forgotten, but the remnants of his massive ship are on display at the Volandia Aviation Museum in Italy.
The Blackburn B-25 Roc
The WWII fighter aircraft, the B-25 Roc was introduced in 1943. Requested by the Royal Navy, 136 were built by Blackburn Aircraft Ltd. By 1943, all of them were retired. The B-25 delivered the Allies one victory. In 1940, a fleet of B-25s stopped a squadron of German Ju 88s, shooting one out of the sky and forcing a retreat. It was a two-seat monoplane with a three-blade propeller and mounted with four machine guns.
The B-25 also had water landing capability, but it proved to be its downfall. The float mechanism caused a crash during testing. Additionally, the bulky floats slowed it down. Only able to hit a max speed of 193 mph, the B-25s were abandoned.
