Fast improving piloting skills. Is it the player or the plane? Did you crash while doing the camera on target? Don't forget for those zoom here zoom there missions to use the LAGM or LASM because those have much longer lock on range.
I want to try the Su-57 Pak-Fa.
If you want to see harder missions, replay using Hard Mode or Ace Mode. I'm playing PSP and in Hard Mode stealth mission to avoid radars, they put in these red light posts where you cannot lock on missiles on them and if you get too close without destroying them via guns or lucky missile, they will spot you and cause mission fail. Another mission, I shot all targets including the special "*" target that appears after you destroy enough targets, except one FB-22 and ammo ran out, time ran out, and mission fail. I guess I had to wipe out all targets. Homing was bad, so missed a lot of shots against planes.
I think Joint Assault had you fly a jumbo jet in very narrow ravine for very long path and cannot fly too high or you will get shot down and you cannot take a lot of damage. I hated that in normal mode. Hard mode will be impossible.
