There was a discussion on these a few years back and some users (me included) posted almost (almost!) all of his airfiles because Alex' website is gone and the files are unretrievable now.

I've just stumbled upon the entire collection neatly tucked away in an obscure archive on my hard drive.

 

The archive includes:

 

- A321

- 737-800

- 747-400

- Beech 350

- C172

- C208B

- DC-3

- Extra 300

- Mooney Bravo

- Piper Cub

And of course thank Alexander for his work.

Nice find! Thanks for making this available.

Hurray for obscure archives on hard drives!

Thanks Bjoern for making these great FDE files available again - and, yes, thanks to Alexander for his original generosity.
