A CF 104 pilot found that the left tip tank yas cap cover was missing when he returned from a training trip . The investiyation revealed that the cap was lost in fliyht .

However, the 5 good show often emotiondl res~onsef is that o ur operational capability will be degraded message containing the direction arrived at the base while and fliyht safety will be cor~ipromised . the S q uadron was awa Y on exercise .

When one remembers that 9 treat your engine like a friend should be? The answer is not simple nor are there any absolutes. There are the difference between an incident and an accident is a so many variables that each situation has to be assessed objectively in difference of degree and not kind the old adage thai "fliyht 10 aeromedevac relation to our collective experience with that weapons system, its role and safety is everybody's business" certainly holds true . the exf~ertise of the people involved .
