I have been following this for quite awhile. The original developer had a feature that would let you jump in a ship, attack ground troops, or fly around in the sky for dogfights. Then, you could seamlessly fly into space and attack one of the big cruisers and have space battles. Then if you wanted, you could fly right back down to the planted you're fighting on. All with no loading.(As seen in the video in the OP.)
When they passed the project on to the new developer, they refused to give them that part. Its a shame. Why they would deny us that feature is beyond me, but its their choice. I only hope the new dev. team will be able to recreate it without having to stop at a loading screen.
