Why do certain planes emit visible gaseous trails in the sky while others do not?

It has more to do with the air conditions than the planes.
All planes give off exhaust from their engines. This contains carbon dioxide and monoxide, some nitrogen oxides and lots of water.
The water is emitted as a gas (steam) that under the right cold and humidity conditions condenses into tiny water droplets and these very quickly freeze into very fine ice.
These conditions are found more commonly in the upper atmosphere, so high flying planes tend to leave contrails (condensation trails)
Low flying planes emit the same exhaust, but in the warmer air at lower altitudes the water content does not turn to water and ice droplets - it remains as an invisible gas.

What skills planes can planes do?
it can fly
Do two planes intersects?
two planes intersect in one line, or the planes could be parallel. by the way there is no such thing as skew planes...
How do you determine the angle between two planes if the planes intersect at a point?
The angle between two planes when the planes intersect at a point is the acute angle fixed by the normal vectors of the planes.
How many planes for symmetry are there in a cube?
9 planes in Cube 3 Planes in Cuboid
What are two planes that do not intersect?
parallel planes
Why are airplanes painted mostly white?
So planes are more visible at the airports at night.
Can planes fly in snowstorm?
Planes can fly in some snow storms but others will cause cancellations.
Who buys air planes from Canada?
It depends if you mean private planes or commercial or passenger planes. For passenger planes I think Air Canada would probably buy planes though I am not sure and I am sure there would be others.
What are airplanes for?
for flying really, but they also can do the different tasks they are built to do(exp. a passenger planes carries people to a certain destination,a bomber planes drops bombs on a certain target etc.)
Do all Vietnamese pilots know how to fly planes?
Some know how to fly planes because they are finished training but others have to go to flight school because they are new. Lots of pilots know how fly planes but others will learn how to fly.
What is an importance of airplane?
Airplanes are very important. We use them for attack, bomber, and fighter aircraft. They also help the military see what the enemy's territory looks like using reconnaissance planes. They help locate the enemy and direct the military to it. Some are used to patrol certain areas. Others help forecast the weather. There are planes that help rescue people, called search and rescue aircraft. And there are some airplanes that even refuel other planes in mid-flight! There are also civilian planes. These planes carry passengers and cargo across the world. Others are just to fly for fun, and trust me, it is fun!
What cannot be brought on planes?
please never cheat others
Why do planes use the jet stream?
To get to a certain location on Earth faster
How did tanks and planes affect the outcome of ww1?
it affected it by the oponents in the war being able to see what the others are doing using planes
What is the tendency of a mineral to break along certain planes?
The tendency of some minerals to break along certain planes is called, "Cleavage".
Why do planes fly high?
Planes fly high to get above the weather, and to avoid air traffic. For jet planes, certain altitudes, all quite high, afford more efficient flight conditions.
Why Red balls are inserted in a transmission lines?
to make it visible to small planes and helicopters.. and even some time immigrating birds
