Baby steps, first DF mission

[Seeker]

I'd like to make a simple practise map for the Stuka for my squad.

I want to run it as a DF, so people can come and go as they please.

Ideally, I'd want an air spawn point over the channel, and some AI flights for fill in, but I don't seem to be able to find out how to make an air spawn point as I'm used to in '46.

So I've got four flights of six stuka's, spaced by about 3 minutes worth of distance, all airspawning in with "change plane" enabled, the idea is they can all pick the first wave, drop, then jump to the next wave, that way we'll get four drops which should be more than enough to kill the little group of ships, game over and we move onto something else... All four groups have identical way points. However..

The first group dive bomb correctly, the second try to skip bomb, the third fly over and fourth dive bombs again.

Now, I've obviously got something wrong somewhere, but all four flights have the same attributes!

So, am I missing something with air spawn points, and is this just funky AI or am I missing some WP parameter some where?
