Mission Editor v 1.8.1 released. Download available here .
Revision changes:
1) Reworked and more randomized ambush conditions and situation
2) New feature added - culling planes/formations that are beyond selected distance from player. Distance is selectable by slider. Idea by HarryH to eliminate processor workload by removing aircraft that are out of active area (especially in later time of war).
3) Small bugfixes

Enjoy!
