If your F-105 is capable of doing something inside its flight envelope, it
is normal operation.

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

How are the flight controls "altered from normal operation"?

What part of the cobra maneuver is outside the airplane's flight envelope?

How do you define "flight envelope" in context?
