Sense of speed..?

[HauptmannMolders]

I've noticed this as well a bit but what is really wrong is the speed with which your plane plows into the ground after you bailed 30 seconds before. I have to assume any plane in this game would dropping nearly vertically, unmanned from 5000ft or so would be moving in the 500-600mph range by the time the hit the ground no? Maybe the issue is the gravity model in this case...
