I think you misunderstand what terminal velocity means. It is simply the speed at which a free falling object will no longer accelerate. But if you strap a jet engine to the back of that object, then it will accelerate for sure. So... no, this is bad. Also, everyone here is saying that 1.0.2 is great and awesome and perfect. Well, it is great and awesome, but have you guys tried hitting the atmo at 3.5k m/s with no heat shield? Well, you should try it... because, you'll be perfectly fine. Heatsheilds are completely useless now. You do not need them. There is no risk of burning up on reentry. So... for me, that's a pretty big broken feature that was just added in 1.0 a few days ago. I wish they'd find a happy medium between the aero in 1.0 and 1.0.2. They tried to make space planes feasible but ended up breaking a simple rule of burning up on re-entry, which is more important in my opinion.
