When it happens, u can go on under some conditions : make large turns (lots of fuel and space wasted), for example, imagine a 19S3 followed by a 22 then a 21 and so on....

This wont give u your enemy tail, but u can manage to make some last frontal passage, so if u got your plane not too much damaged u can blow some shot again. Otherwise if u dont like to retire just go around and waste your fuel and finally exit from a side
