A valid question.
I understand that in future conflicts the 1st (Duke of Wellington's) Kings Defence Contract Enforcing Battalion are to be in the vanguard of our war plans. Not until the appropriate paperwork, with liability and risk assessments, has been signed by our potential foe shall the aircraft be sent into danger.
In the event of the enemy objecting to this, we shall threaten to ignore European working time directives and threaten to fight at weekends, evenings and on public holidays thus scuppering their own financial plans. They'll sign.
It's a fantastic and clever calculated strategy that makes me proud to be British. Both our soldiers, the sailor and the airman that are left in 2020 shall have a strategy fit for purpose.
