The invention relates to arrangements for land airplanes for preventing sinking in emergency alighting on water. Boat seaplanes or float seaplanes, that is to say, pronounced hydro-airplanes, are of course prevented from sinking in consequence of their construction. Owing to their special lay-out....
They are much smaller, so they can land in small places. Helicopters can do many jobs that airplanes can’t. They are used to lift heavy things or fight fires. Helicopters can carry buckets of water. The pilot flies over a forest fire. He presses a button to dump the water onto the ...
Sure, humans evolved to thrive in Earth's atmosphere, but it's important to realize that we only evolved to thrive in a thin layer of the planet's gaseous outer layer. Air pressure changes depending on altitude. In the same way that the water pressure in theoceanis greater on the seafloo...

Imagine how steady you have to be in order to accomplish that sort of thing? The pilot has to counter every little blip for a rescue mission like that to succeed. Blips like wind, or if in the water, the waves. The people walking inside the helicopter also produces bounces. I would be...

That’s how we go on downwind – keeping the plane down and managing our power to keep the speed from going up. Abeam the numbers, I bring the prop RPM back to no more than 1900. A moment later, I’m turning base leg. I glance over at you – your still smiling. ...
Think of all the things that make our world modern.Airplanes, highways, computers... We have many choices for almost everything, including food, phones, paper, and so on. All of these choices are created by engineering. Engineering is a subject of science. It is about using resources ()...
