Why do journalists insist on doing this:
Take a look at the video and tell me if that is what you would consider a crash landing:
You are in heaven as you just signed up for your 1 month free porn subscription, and want to stream and save as much smut your internet link can handle, because you are a lonely looser nerd that needs to stock up on material for the long winter ahead. You run as fast as your legs can carry you to your favourite shop in the whole wide world - Best Buy. But alas - so many options to choose from when trying to buy that huge external hard disk drive.

Like the one you tell your kids just before an atomic bomb is being detonated - "Everything will be OK, I promise".
