This time, players were assembling planes (I-180S) and were able to trade them for another reward - VFW or Project 122bis (for one figher), or Merkava, Ju.288 or HMS Tiger (after assembling 3 planes). PS4 players were able to choose the reward, too, there was no need for Marketplace. Most events have rewards for both tankers and pilots (and since recently - sailors, too). In most cases they require some sort of skill (such as "Chronicles of WWII" event just a year ago), but in the "Battlefield Engineer" you simply recieved parts by spending time in combat with 50% activity. Lose control? You mean your pilot faints because of G-force, or your plane stalls?
