So picture the scene in a Tornado crewroom a number of years ago or indeed in a Typhoon crewroom next week. Station Commander breaks the following to the crews:
"OK chaps, we have enough money to run 4 Squadrons of Typhoons if you are happy to look out of the window and hope for the best or we can fit collision warners to 3 squadrons of Typhoons. What shall we do?"
Wonder what the crews would say?
