From the looks of it, the containment chamber and the Hulkbuster in *Avengers: Age of Ultron* seem to be floating in Earth's orbit. My question is, how did it get to Wakanda in a matter of a few seconds from the time of deployment? Is it really how long it takes for something from Earth's orbit to reach Earth?
