How to make a balloon fly

How does a hot-air balloon work (in theory)? In a word: buoyancy . Hot-air balloons float in the sky for pretty much the same reason that boats float on the sea. A boat floats because it's supported by the water beneath it: the weight of the boat (pulling downward) is exactly counterbalanced by the pressure of the water beneath it (pushing upward). A boat doesn't float perfectly on the water surface but sinks partly into the water according to how heavy it is. The bigger the boat, the bigger the area of water beneath it, the greater the force of the water pressure pushing upward on it, and the more weight it can carry. Here's another way to look at it: generally speaking, an object will float if it's less dense than water (in other words, lighter than an equal volume of water) and sink if it's more dense (heavier than an equal volume of water). Imagine a block of lead the size of your arm dropped into a bathtub filled with water. An "armful of lea...

What is the Difference Between a Jet & a Plane?

One of the most common types of airplanes in use today is the jet, which has largely replaced traditional aircraft powered by propellers. Although propeller planes are still used in some instances, jets dominate commercial and private air travel due to their greater speed, ability to fly at higher altitudes and mechanical reliability. General Airplane History While efforts toward powered flight date back to the earliest inventors, the first successful flight of a fixed-wing aircraft was performed famously by the Wright brothers in 1903. Their plane, known as the Wright Flyer I, was made of wood and used a gasoline engine to spin a pair of wooden propellers. Over the next several years, the Wright brothers continued to refine the design that would provide the basis for aircraft over the coming decades. World War I provided a major incentive for the design and construction of better airplanes. Planes were originally used purely for surveying the enemy's positions. This l...

Protecting your wheelchair

As with all luggage, you should tag your chair with all your contact details, name, address, telephone number and hotel address in the unlikely event that your chair goes missing. Ideally, you should also attach a photocopy of instructions to dismantle to your chair. If your chair requires any special equipment for disassembling, discuss this with the airline in advance so that they accommodate your needs. Remember, even if you are on hand to help with dismantling your chair before departure, it is unlikely that you will be present at the other end of your flight to assist with re-assembly. If you encounter any problems, then you should immediately speak to the 'Complaint Resolution Officer'. All airlines should have a CRO officer available 24hrs a day either by phone or in person, who is trained to deal with any problems a disabled flyer may encounter whilst travelling. Disabled travellers in the U.S. can order a free booklet from the U.S. Department ...
