The discussion of formation flying has dredged up a 50 odd year old memory. A year or so after 360 got the T 17 life started to get more interesting with increasingly challenging profiles, at least for this first tourist and by now the only fg off captain in Signals Command/90 Signals Group. One morning the programme detailed a 4 ship for some exercise. Boss briefed the sortie. "Any questions". "Yes, Sir" quoth I, I have never flown a Canberra in formation." "That's OK, its mainly a box 4, you go in the slot and follow me." I was doing quite well until he called the echelon for the run and break on return.
