What you see is not smoke- they are contrails- short for condensation trails. The air is extremely cold at that altitude, the exhaust is hot, and contains a great deal of water vapor. When it comes in contact with the cold air, it condenses, and becomes visible, like fog or clouds. Ever see the "steam" roll out of the bathroom after a hot shower? Same idea.
because the airfoil shape makes tiny air molecules at the bottom slow down and the top speed up. The engine just pushes the plane.
Examples of horizontal lines in the real world include the horizon where the sky meets the land or sea, the straight line of a calm lake's surface, the boundary between the wall and floor in a room, and the straight line of a ruler placed flat on a table. Horizontal lines are parallel to the horizon and perpendicular to vertical lines.
Vertical lines communicate a feeling of loftiness and spirituality. Erect lines seem to extend upwards beyond human reach, toward the sky. They often dominate public architecture, from cathedrals to corporate headquarters. Extended perpendicular lines suggest an overpowering grandeur, beyond ordinary human measure.-eNysH2gm_eNysH2rc
5 pointed star? 6 pointed star(star of David)? A star in the sky? You need to provide more information. A 5 pointed star can have 5 lines of symmetry.
look in the sky and you will see it
the government is honeslty trying to posion us.. its called a chem trail.
The streams that jet planes leave in the sky are called contrails. Contrails form when the hot, moist exhaust from the airplane engines mixes with the cold air at high altitudes, causing the water vapor to condense into ice crystals. Contrails can sometimes linger in the sky for a while, creating long white streaks behind the plane.
they are planes that go above in the sky during war and drop bomb.....
plane fly in sky
planes birds stars and what not
No only on planes.
Sometimes when the sky and storm are many in the sky, the sky will look a kind of white.
Almost all aircraft flying in the high, cold sky leave contrails. These are trails of hot air from engines running in very cold air. In World War 2 the bombers going up high in early mornings left very visible trails.
If the lights are moving, it is most likely they are planes. If the lights are not moving, it is most likely they are stars.
