I can see what you are trying to show but in my non-mathematicians mind I would say the first paragraph is correct because it is pertinent to one crew at a time and only when they fly (and because all 94 crews could never be airborne at the same time). There will be an element of "fudge" for the number of military aircraft airborne at any one time (which may be higher or lower at any particular time of day or location). If the figures in para 2 were correct most RAF aircrew would have at least one midair per year (based on an average sortie length of 1.5hrs)!
