That did bug me from the moment they showed the cars...I was like "Oh this'll be cool they're gonna dump them while they're taking off.....nope they just lifted....oh ok they're gonna dump them while they're trying to make the climb...oh ok....oh ok now they're gonna dump them when they're low on fuel" LMAO....my girlfriend elbowed me after awhile.
They kept the cars in case they needed to make an emergency exit on some 20,000' high glacier in the Himalayas. Wouldn't everyone?
Also like how the American's screwed up their ark with a piece of garden hose, then collided with the innocent Europeans turning their Arc into the 2012 version of the Titanic and thus consigning several of history's greatest civilizations to the history books. Go USA. Go garden hose. Never did like Angela Merkal anyway.
On the plus side, my missus does finally see the value in me taking flying lessons. I can't wait to make the step up from my Katana to the Antonov.
