100 hours is a long time? Per tour? Per ?
Each tour, only about 3% of the recorded pilots have 100 hours or more of 'time in sortie'.
For the record, my personal 'best' (or worst, depending on how you look at it) was 235 hours... and of course that did not include time in tower watching the map or planning the sorties (which would add at least 25 to 40 percent). When I was a regular, I was approximately spending 130 hours per tour "in sortie", of course you would again have to add planning time, time spent as a trainer in the TA, doing stats stuff and helping players on the BBS and such...
