Roll rate... ?...
400degrees/sec? not even close. that has an extra "0" in it... and is still wrong for the B767 or B757.
at high speeds, exceeding VMo, the wing "such as" on the B757 can result in roll reversal occurring, (have seen 2 separate sets of data on similar configurations where this has occurred).
A4 roll rate is noted fairly accurately, it will mess with the side of your helmet.
For jet transports at high speed, the flightpath vector is not going to change substantially without pulling extreme g loads, and that will pretty much mess up the wreckage location.
