Ok, well this isn't the abomination floating mid air, but rather your character, I'm sorry if this has been posted before. And I must warn you, it's rather useless.
In order to do this you need the quest "Warning: Some assembly required". Now go to the edge of say, a small hill, right click the assembly kit, once the bar is at the end, there's a pause of about 1 second before the abomination spawns and during this you'll have control over your character, so jump, or jump off the hill, and you'll be in mid air. It'll take a little trying to perfect it SO I suggest you start at the edge of a hill, and when the things done and before it spawns run and jump, and the thing will spawn and you'll be able to see your character floating in mid air.
Rather useless but it's fun.
Here's some pics:
