Dude you are a bridge troll. Stop dispensing nonsense. Virtually all modern commercial airplanes, up to the recent explosion in carbon, are primarily aluminum. And I'll bet you don't like carbon either. Racing motorcycles are made of aluminum. I have a 10 year old MTB that I used to whale on that I now use as a round town bike to take my kids on rides. So stop trying to fill people's heads with what amounts to fear mongering lies.
