Aircraft Carriers


Landing an aircraft on an aircraft carrier at sea is considered the most difficult task in aviation. The first aircraft ever landed on the deck of a steamship was accomplished in 1911, just a few short years after the Wright brothers had the first airplane become airborne. The task was accomplished by having ropes and sandbags run horizontally across the wooden landing stage on top of the deck of the ship. The rope caught a hook on the bottom of the landing aircraft and slowed it down, with each bag adding more and more weight. The engineering of this practice is still in use today, with the only significant difference being the components used, which are now high tension steel cables. Marines and navy officers jointly train for their wings, but navy officers are more likely to take off at sea, whilst marine officers are more likely to take off from land

Challenger Spacecraft


The reason the Challenger space craft exploded 73 seconds into its launch on January 28, 1986 was because the temperature the morning of the launch was -1 degrees Celsius which caused the o-rings placed around the rocket’s boosters to shrink and leak fuel upon liftoff. This theory was brought to light by Valentina Tereshkova, who was the first woman in space. Tereshkova relayed her theory to one of the heads of staff at NASA who then relayed it to Richard Feynman by showing him how vehicle carburetors which also have o-rings experience the same issue. If the ambient temperature is below 11 degrees Celsius this issue is a common occurrence with all o-rings, regardless of the vehicle or craft it is installed upon



At any given time there are approximately 1,000,000 (1 million) people worldwide upon aircraft which are actively flying. The average commercial passenger aircraft weighs 100 tonnes, lands on a runway 150’ wide, and lands at 240 kilometers per hour whilst dropping at a rate of 10’ per second. Approximately 100,000 flights occur daily worldwide. Rolls Royce aircraft engines travel 16,000,000 (16 million) kilometers in between servicing and as such, they have sensors which send wireless data in real time as an aircraft is airborne. Most aircraft and their engines now employ this technology behind the scenes as a safety measure to ensure every flight goes smoothly. There are approximately 35,000 parts in each aircraft engine. Aircraft engines spin at 150 revolutions per second making them spin 9000 times per minute. Statisticians estimate that flying is up to 50x more safe than driving a vehicle. Approximately 7 in 1000 luggage bags do not meet their destination on time and approximately 1,400,000 (1.4 million) luggage bags per year never reunite with their owners due to lost tags or abandonment. Unclaimed luggage eventually goes to auction due to space requirements. Approximately 50% of every aircraft can be reused and the other 50% can be recycled. The most expensive and sought after parts to reuse are the engines and the most expensive and sought after parts to recycle are aluminum
