Seems a strange thing to have to unlock.
I mean, ships have guidance systems, they can get through normal space and hyperspace, etc...but SOMEhow just can't manage to let you pick a spot on the planet for landing.
...makes perfect sense.
If you want me to unlock a power like that, make the landing-safely spot really small at the beginning and then let me unlock the scientific discovery (or the alien tech purchase) that widens the circle, making landing damage less likely.
