@SSquadleader:
There's never been a planesman cap. Document yourself.
The planesman air reload formula is this (from Adalbert):
T(rel) = 112 - 20 * (true ability/10^6) [seconds]
Meaning, if your planesman's true ability is higher than 4.6 M, your air tank refill time is lower than 20 sec. An EBVE KM planesman at lvl 97 (2.3 M TA) still needs 66 sec to refill the air tank. Vet cap him (290-300 vets) and you're already down to around 40 sec.
@Stabbyy2: you've just been spouting mental diarrhea, as has your admired ozzy0 (I'm not saying he's not a good player, but that last post of his here was rubbish).
@HeroEnVec: add to that the critical dive bug.
