Question

Why airplaines generate white smokes while flying?

Answer 1

Yeah, the cloud is a trail of condensed, liquid water droplets.  The water was vapor in the air, then it condensed into liquid.

Answer 2

White smoke means they have elected a new pope.

Actually, it is the frozen condensation of the water in the fuel, which is very hot until it suddenly contacts the outside air, which is very cold.

Answer 3

DRINK

Answer 4

Its the exhaust from the engines.

Answer 5

This is no form of smoke. Its water vapour. Water vapour is a byproduct of the air reacting with the fuel. These trails are called contrails. Meaning condensation trail.

Answer 7

It is a conspiracy!  The White clouds is really mind control agent that the governtment puts into jet fuel and they are making us more compliant.  Thats why the government keeps bailing out the airlines and why the government runs the Industry (FAA)

Answer 8

That is not smoke it is called a contrail.  It the water vapor from the exhaust freezing as it cools to below freezing temperatures in essence making a man made cloud.  if you see a contrail then it means that the aircraft is flying at over 29-30 thousand feet MSL.

Answer 9

because it works with white petrol hence its simple

white petrol=white smoke :-)

Answer 10

accualy you are refering to jet aircraft . what you see that looks like smoke is a vapor trail. the atmosphere at high altitudes is well below  0 degrees and the heat comming from the jet engines leave steam.  it is usually a millitary aircraft as they normally have to fly higher than civillian circraft
