In a recent question asked here, it was asked what debris falling from a Rocket Lab Electron Rocket was during launch.
The answer, was that it was ice that had formed after cryogenic fuel/oxidiser tanks were filled, and that vibrations/other stresses caused it to fall off during launch.
This lead to a comment:
Why don't American and Ariane rockets seem to have the same problem?
Why don't they have this problem? Or do they indeed have the ice problem?
