If your F-105 is capable of doing something inside its flight envelope, it
is normal operation. You have to remember that I have been harrassed here
for years over claiming our F-106s were capable of mach 2.3 without
damaging
the airplane.

An example of an abnormal operation is the cobra manouver, as the flight
controls are altered from normal operation.

As I said...a very 'interesting' definition of the word normal.
