Offcourse it's very nice if you can manage and can do the real thing but for those who are not that lucky:
My neighbour has done it all: fighterpilot (F104 and others) and captain (767 and others) and now he is retired but ................ loves it to flightsim and esspecially with carriers because he did never do that in his active job.
Morale: a pity, that we cannot all do the real thing, but, when even a guy who has flown the real, loves to flightsim, it's not that bad after all.......... and: we are very fortunate that there is such a nice flightsim as DCS!!
