"If you are getting bounced from above..you really run out of options..and you may need to give then enemy the shortest akmount of time and plane surface to shoot at ..which would be to HO pass.... " - by BGBMAW
If you are referring to the typical 'turn and face the enemy' type of aggressive defensive against BnZ, that ain't no HO - You turn towards their direction of the Boom sequence, thus, giving the attacker a very high closure rate and steep angle which makes it very difficult to hit anything. Typically the defending plane passes under the attacker - it's a front quarter shot for the attacker, not a HO.
Now, when a plane turns into the Boom sequence, and noses up and meets the attack with guns blazing, that's HO, and it is avoidable.
