Aircraft Sinking In The Ground

Earlier today I was taxing to the active runway in Chicago and there was a Delta ERJ-170 in front of me who had just been cleared for takeoff. The guy acknowledged and then he sank into the ground at a very slow rate, then he popped back up and then teleported halfway down the runway. The teleporting thing is lag, I’m just curious about the sinking thing.

Northwest Airlines Rocks!

Have you re proed this? What device are you using, and what type of update of IF and software update on you device?

Sometimes I see aircraft sinking into the ground upon landing and then disappearing. Is that what you are talking about. I think the airplane just crashed when that happens.

No, it just started and then shot back up during takeoff before rotation
