The start of a barrel roll from the P-8 crew's perspective must be almost indistinguishable from a collision turn.
there ya go, and the natural inclination of the aircraft being "threatened is to turn away from the threat, right into the path of the Flanker completing the maneuver. After the P-3, Hainon incident, there is no danger of anybody grading your airmanship very high for a long time, this just leaves a bad taste for any pilot, its like some idiot on sport bike on I-70, doing wheelies and stupid stuff during rush hour, and putting your "family" at risk. I've had the displeasure of having to ride through several displays of "stupid", NO THANK YOU! but I'm rather sure the Flanker performed as advertised, and it is a very fine airplane for the mission, fast, maneuverable, speed brake, lots of goodies to help you perform a "safe and effective" intercept, take the pictures you need, and ride shotgun till the other fella is tired of "sightseeing", that is the Flankers forte.
