Get it on tape
Whenever I came across this attitude in a certain fast jet I would calmly announce the following so that the voice recorder would pick it up
"For the benefit of the Board of Inquiry I wish to state that I, Flt Lt *****, service number ****299R, have instructed the pilot, FLt Lt ********, that he should refrain from flying at ****ft in the area of *******. The Flt Lt in question has decided to ignore my advice"
This usually worked!!.........
