Hello Commanders, it's my first words here.
How I did this mission last Saturday, after lots of savegame reloads and forum reading trying to dig mission information and hints:
My Ship: Osprey X (named "The Universe's Photographer" because my preference to do classified missions...). Its regular equipment is a Military Class 2 Driver, 1 shield unit, 5 MW pulse laser, auto pilot, navigation computer, jammer and cameras. No atmospheric shielding (it's a bug, i can fly low and land on planets without it most of the time). No radar mapper and scanner.
To this mission I configured the Photographer with the following equipment: 2 shields units, 1 MW pulse laser and 4 MV missiles.
I took of Birmingham on 25/Jul with 1 ton of fuel and my escape route traced to Urandol. Accelerated to ~99000 Km/h heading to "a little bit" above the planet horizon where the academy was.
When I was about 2500 Km from the Academy, at an altitude greater than 40000 meters I shoot the retros to slow the speed. I flown over the Academy at a speed ~40000 Km/h, maintaining the high altitude. So I shoot the missiles and touched time control.
With the "done" written at the mission roster, I pressed the hyperspace button without hearing any "ship is under attack".
My strategy was based in the fact that to use time control properly, I could not be under attack. And a high speed pass over would work.
Well it worked to me.
I have the savegame just after read the "done".
I hope help someone. I tryed others strategies (low fly, ie) but it did not worked to me.
bye!
