there can be many difficulties when flying paper planes including rain and other weather issues, interruptions (people, animals and objects passing by), extreme winds, injuries (papercuts, flying a plane into your eye or a bystanders)hope this helped :) :)
Flying planes.
Some other kinds of objects used as currency is salt,furs,grains,and gold.
They have to stay away from other planes so flying at different heights gives them room. Several can be "stacked".
I think it's just the order the objects are thought of when guessing at what "that object in the sky" is. Planes are often named after objects other than birds. Cherokee's, Cessna's, Mooney's and Lear all all examples of planes not named after birds.
just grenades and other chemical filled objects
they're flying craft (like planes, helicopters, etc) that are not claimed. Like, the government and civilains dont know about them I'm sorry, I didn't see the "in" in your question. Nobody really knows what is in them but I asume other worldly creatures or people who work for the government if you believe that the government is in control of UFO's
Some may be top secret military planes during test flights. Some could be weather balloons and still some may be regular aircraft in the night sky.
ya No, they took turns flying the planes. But, they did go to Kitty Hawk together
If you are flying from New Delhi, India, to Sydney, Australia, you would change planes one time in Bangkok. There are other routes but you would have to change planes multiple times.
Aerospace is basically 'Rocket Science' and is separated into crafts that operates in the Earth's atmosphere and in space, and has to account for atmospheric pressures and the such. Aerophysics, on the other hand, has to do with the physical design and construction of aerodynamic objects, and has to account for the materialistic matters. In other words: Aerospace= theory of flying objects Aerophysics=physics of flying objects
Sometimes you can come across some sporks in space because the moon has those kinds of utensils.
