IMHO the crashed lobster isn't a ship. It's the weapon (projectile/drone) the actual mothership launched at the Annies and T9. The crime scene shows the victims and the crime weapon/projectile/drone.
Not the assaulter. That's why no cockpit. That's why they crashed all together on the same small area. One single shot and... OMG !
Let me just put these points forward for your consideration...
- There's a lot of evidence to indicate that what's at the crashes and what's in the encounters are the same type of ship
- The area where the cockpit would be is underground at the crashes so it is not possible to say there is no cockpit
- At the original crash site there's are no crashed Annies, no crashed T9s and in fact no debris of any kind that does not exactly match the ship from the encounters
