I have a few questions about integral airstairs?
1. Can the Airbus 320 series be equipped with them? I've never seen one with them, but they would certainly be useful.
2. I seem to remember hearing that some airline (SY?) removed some from 737s. I want to know if a 737 built without them can be retrofitted with an integral airstair.
3. Are any widebodies other than the VC-25s and Il-86s equipped with them on the lower deck? Can they be retrofitted and are any of the VIP 747s going to get them?
