I broke the sound barrier in the arado last night. I died though. I went up to 30,000 feet, then put it straight down. At about 400mph I fired up the RATO units. Of course, my wings ripped of shortly after, and I became a flying hot dog, but oddly, the RATO units continued to work on my acceleration. Even though they are attached to the wings, the wings went but the RATO units stayed. Oh well. Anyhow, I took a screenshot that I can post here later of the inside, note the spedometer pegged back to zero. I must have been doing close to 850mph at about sea level. Actual altitude will be in the screenshot as well.
I don't consider it official since I died, but I will set wind at 127mph in a terrain next, and try to do it officially.
Has anyone else tried to do break the sound barrier? Am I the only one who plays around like this (understand that I did this in offline play).
