Hi Guys

Basically SDI is right. When the prop blades have to start moving faster than sound they start cavitating the air around them (i.e. creating vacuum pockets) and end up destroying themselves. Messy.

Was a good TV series on the race to break the sound barrier that covered this. I think it was a BBC documentary.
