The US mountains where 1500AGL is over 18K' are all in AK. There is also no
class A over the Aleution Islands.

Uh....if you're between 18K and 60K in the US, then you are required
to be on an IFR flight plan, hence only at even number altitudes.
33,500 is inappropriate.

That's not correct. You're required to be on an IFR flight plan in Class
A
airspace, but not all airspace between 18K and 60K in the US is Class A.

By the way, 33,500 IS an even number.

My bad. I meant all thousands, not the half thousands that we're
used to in VFR.

Second my bad...what airspace in the US 18K and 60K is not
Class A? Not counting the big mountain in Washington state. (sorry,
can't remember the name)
