Huh? The way I've always understood it is that heads fly from the air entrained by
the disk surface as it spins, not from air blown through the drive via the air filters.
And clearly that is true for modern drives, since they are sealed.

I vividly recall a log by an operator who had a
bad CDC 844 pack who
proceeded to destroy 5 drives and 3 additional packs. It was detailed
enough that it read like Gerard Hoffnung's "Bricklayer's Story".
When I was testing one of my RL02 drives I had a head skid on the disk. Problem was the
air filter was so clogged there wasn't enough air to allow the heads to fly.
