Why nitrogen?

Bertie:

I find this hard to swallow, and I doubt that oxygen (at 20% of air),
regardless of pressure, is going to cause a detonation in an oleo. Just like
in a tire, the percentage of oxygen remains the same, so its ability to
support combustion also remains the same. Now, the increased oxygen pressure
might slightly increase the risk of corrosion, but we are not talking orders
of magnitude higher compared to ambient. At least this is my understanding
as I recall from being a chemistry undergrad and grad student.

The more I hear about this, the more I think it's an old wive's tale.

Anway, what did you think of Anthony's claim"it's not me?" What a moron.
