Hi,
Thanks for the fast reply. :)
I was intrigued by the bombs because I also saw the video with the corsair II who was dropping a LGB. ;)

It's with the tutorial Mission & Battle Ground editor that I have a problem.
When I go to the website page with the address you gave, I have all written explanations but no example images. :-?
I tried with my other computers and with the computer from a friend but it is the same problem.
Let me know if there is another tutorial in pdf or other...  :)
