Pilots,
One of the latest features to hit World of Warplanes is Plane Birthdays. You probably caught a briefmention of them in our summary article for Update 1.8, but here's the tell-all featurette--read on!
1.8更新内容里提到过飞机的生日，现在我们详细说下这个东西

These plane birthdays will be happening for all planes starting at tier II, regardless if they are regular
planes, bought Premium planes or granted gift planes.
The bigger the birthday, and the higher the tier of the aircraft, the bigger the birthday gift will be.
Here’s a preview of what the “Birthday Gifts” will include:
400 to 10,000 free XP
Double or Triple XP or Credits for your next 7-20 victorious battles
Birthday Emblems
Premium Account time
只要是二级或二级以上的飞机都可以得到礼物，飞机等级越高，奖励越好。
礼物的内容：
400—10000全局经验
7-20局胜场双倍经验或银币
生日徽章
折扣

Of course, already purchased planes that have passed their birthdays by the time the feature goes live will also receive their birthday presents. Look forward to collecting the complementary One-Year Emblems when you log in the first time on 1.8 for every plane that’s been in your hangar for 12 months or more.
当然，这之前已经买了的飞机也会收到礼物。在机库中保留至少一年的飞机就可以收到年度徽章。

接下来看一下开发者日志

Greetings, pilots,
Many of you, upon entering the hangar today, must have seen a new message, notifying you of a birthday for one of your planes. This is a new feature that we’ve added to World of Warplanes.
进机库的时候你会看到我们的通知，有关生日的消息。

We want to also take a moment to right away address some of our veterans, who have managed to amass dozens of aircraft in their well-equipped hangars already a long time ago: Many of you will have bought your trusted warbirds over a year ago, which is why the system only gave you their corresponding birthday emblem but not the associated birthday mission, which would have contained another prize. This happened not only to you, but to everybody in this situation, including us. One of the main goals of the Plane Birthday feature is to encourage players to unlock new planes in order to rise up in the tech trees where stronger and faster planes await. Granting the supplementary birthday gifts to players, who have many dozens of planes in their hangar for more than a year at once, would have significantly disturbed the in-game economy. Therefore, you will only be able to receive all birthday missions (and their connected gifts) for planes that will celebrate birthdays from today going forward and not those that have been in your hangar for the longest time.
对于之前就攒了很多飞机的老玩家来说，很多飞机停在机库里都有一年以上了，对于那些飞机，如果直接给予大量奖励，会扰乱游戏的经济系统，因此，它们只会有徽章奖励，而没有生日任务以及相关奖励。只有更新以后飞机才可以开始获得那些奖励。

See you in the clouds for your next big sky-birthday, pilots!
掰掰！
