Airplanes Crashing

[OKO]

You can see an exmaple of what I made (with really looong tests to find a correct solution) on the mission MP6 Harpers chase
I juts gave transit WP to planes until they reach a trigger when I ask them to attack.

If I ask them to track or to attack from the biginning, they always finish their course in the water long time before they reach the target, or engage the target out of range, so they just lost their weapons.

When I tried simple things like transit and attack order when they reach the last WP, they just started the attack from the beginning and didn't wait the desired WP ... (so lost their weapons at this long range)

I was also forced to put them at high altitude in transit mode to ensure they can reach the attack trigger without falling in the water.

It cost me hours of tests before I understood how to do here ...
And they still sometimes fall in the water ... (but really not often now)
Planes are difficult to manage, and quite buggy ...
