Hi today I have shot two planes down with tank not one registered as a kill, then later I was definitely shot down by a tank it said I had crashed I am sure it something to with update anybody else found this problem

If you are looking at the ranks/stats, note that Joaquin changed the update frequency of ranks to once per day (not sure what time of day). I don't know if it's just ranks that don't update, or if all of the stats don't update, until that magical recalc time. Plus, the recent rash of tank spawnkilling had him concerned enough to add plane immunity from tanks while braked (and possibly while on the runway but I'm not sure), so maybe he messed with tank kill credits. Being that I love it when I'm able to blast a plane out of the sky with a tank shell, I sure hope he didn't change that credit. But I guess I succeed so infrequently it hardly matters.

No it wasn't on the runway

I understand that your kill was out of the sky. It's just that while changing the game to deal more fairly with runway tank spawnkillers, Zup *might* have removed tank kill credits or something like that, I don't know for sure. Just throwing in that partial piece of information plus some speculation to see if I can help solve the apparent mystery.

My observation from both "killing" and being killed via tank on plane... I direct hit still registers as a kill. I was hit yesterday. It scared the beejezus outta me. Loud explosion followed by my plane flipping and rolling erratically and of course the message that said Parrot just got his arse handed to him. I treated some else to the same experience a day or two ago.

Now if a tank shell explodes "near" a target it will throw the plane out of control and if its flying low it will usually crash and register as such. I took off from a carrier just the superstructure was hit with a tank shell and went into a horizontal spin. But did not crash.

I think it has to be a direct hit to be a kill.
