For having checked their webpage again a few months ago, I’m sure Airliner XP has kept for all this long time their website up and running. But it has been updated as well.
The homepage layout changed, now you can read “Copyright © 2006-2012” at the bottom, … and a short announcement of A320 Airliner XP “released shortly for FS9 first and FSX later, followed by the A330 and the A340.” Hands up !
If you are new comer in the FS community, Airliner XP made early announcements of such A320 project “many” years ago, involving some famous artists and experts in their first product developement with this brand new company. But then we haven’t heard much about them, just a few previews in 2007 and then nothing more.
While I’m writing about an Airbus project and designers in stealth mode, do not worry too much about NLS A380. Their website http://www.nextlevelsimulations.com/ is down, but their facebook page says it’s due to “refurbish reasons”.
