[ I was an NFO, and I challenge those guys out there with there 1000s of hours of autopilot jet time and see if they could handle a low level flight at 500' AGL going 300 kts. I guarantee you that you couldn't do that, unless of course they are prior military.
Try 200' through Red Flag excercises (north of Nellis AFB) going 400 kts (speed limit of a B-52)
