Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
there is 9 planes of symmetry in a cube
There are 31 planes of existence in Buddhist belief
The intersection of two distinct planes is a line. The set of common points in the line lies in both planes.
The air molecules in the stratosphere are far apart. This causes less wind resistance and allows planes to fly faster and achieve better fuel economy.
They go into hangers.

Planes are usually kept in hangars, which are like huge barns with sliding doors.

Yes, jet planes are that - planes, whereas airlines usually refers to a company that uses planes to ferry people around.

Far apart.
Electron pairs are kept as far apart as possible as molecules adjust their shapes according to the VSEPR (Valence Shell Electron Pair Repulsion) theory. This theory helps predict the geometry of molecules by minimizing the repulsion between electron pairs in the molecule's valence shell.
No! there been even worse ones like planes exploding. The tail falling off planes then the plane crashes. Planes braking apart on the runway.
Quite far apart I'd say. There is an ocean in between.
