When scripting with the Extra Large Hangar Door:
1) Property Status never reports "Opened"; doors that are opened have status "Opening". "Closing" doors eventually reach "Closed". This issue is critical because it makes the doors effectively unscriptable if you are waiting for the doors to open.
2) Property OpenRatio is either 0 for "Closed" or 0.4 for "Opening/Closing". This is minor but maybe related to 1)?
3) The doors are Interface IMyAdvancedDoor instead of IMyAirtightHangarDoor.

As well, probably related to the Extra Large gate being airtight while open, but you cannot build blocks in the gate path.
