Adding aircraft to the LHA flight deck

[gray eagle]

I stumbled on a page that offered a way to add additional helos or other aircraft to the flight deck of the freeware LHA5. I wish I had downloaded it now, I cannot seem to find it.
It mentioned that now your aircraft does not have to be alone on the flight deck of the LHA and I believe it would spot other helos as well.

I am interested in adding AI aircraft to the flight deck if possible.
