I am a bit disappointed. After the 2500m/s cruise part at high altitude, the ship was limited to its designated maximum normal/boost speed - even while flying down. Does that mean each ship has - in vacuum! - a terminal velocity identical to the speed it can achieve under its own power? Because that would mean an Anaconda falls slower than a Viper...
I was expecting that our ships would gain speed well beyond its normal capabilities when diving. Instead, the Eagle is boosting just the same way as in deep space.
Edit: On 2nd thought, maybe this is just FAON doing its job, using retro-thrusters to keep the speed within the designed limits. If we turn FAOFF, will our ship keep accelerating downward according to gravitational acceleration?
