Frenchy gets his face closer to TAC's face and cannot help to notice the distinct blue eyes of the humans who spent too much time on Arakis without protection.
Easiest planes are the ones who don't have nasty stall characteristics like Spits, Nikis, F6s, Yak9, Zeros. The experten planes are the ones without canons who are neither the fastest or best turner. The P47, F4 comes to mind.
The rest are great "transition planes", the fast ones like the P51s, they teach the newbies to do something else than simply turning, but still offer the possibility to run when in trouble and survive. The second type of "transition" planes are the cannon ones, likes the FWs and 109s. They are tough to fly and require discipline but a couple of pings reward the the newbie with an instant kill thx to the fire power.
