I was fortunate enough to have my clan mates on my side during this special event for World of Warplanes called Japanese Threat. It is basically factional warfare (Allies vs Axis) and the event gives you loot crates based on how much you contributed to the war. It lasts for 2 hours or until the amount of hit points a faction has runs out. So far it's my favorite event ever in the game. As far as the loot crates go so far I've received a bunch of gold, free XP, and some high tier equipment for my planes. The potential to unlock free, fully researched planes is there.
