Perhaps you could quote the part where they specify what the leak was and how much?

Then you need to read the article again. I’m not going to quote the part where they specifically say what part failed and what tank it was attached to, which should give you a very big clue as to whether it was methane or LOX.

Unfortunately, the *precise *volume in cubic metres wasn’t specified. The effect that it had on the nosecone and temperatures of various sensors in the nosecone was mentioned, which implies it was more than just a trivial leak. The loss of the ship also implies that.

edit: Oof my instance is slow today, multiple duplicated comments deleted.
