I found the source of the pics and the answer to your question.
It's from one of my active loadout screens. On that map the bomb drops into that location by spawning high above the map (about a 7 second drop) to prevent players from passing to their teammates by tossing it off the floating map and having the bomb respawn at center.
The Breakneck one was always my favorite.
I like to think people liked my Downlinked loadout cam
