Frank, were they digging the foundations for a new ergonomic worm farm? Or perhaps they ran out of carpet to hide things under so with all the current heat on them they decided to 'go big'! Maybe that photo is actually a photo of Sky Sentinel, the $3 million dollar lemon? Is that what it does with collected information, buries it? Perhaps that pic is a premonition (bit of voodoo hocus pocus) of a future crash in a muddy swamp where retrieval of 'bits' is being undertaken?
Then again, it could be Senator X at the wheel of that robust excavator, digging a channel wide enough for the Styx Houseboat to make it to Fort Fumbles front door and pick up its nervy passengers!!!
TOOT TOOT all aboard, TOOT TOOT
