Sadly this was a no go.
Rob (runkthepunk) did some investigation work on this, and the site is an ex-MOD location which is incredibly difficult to get into, so getting anything out, even a monitor, would prove very difficult.
I don't want anyone to risk anything trying to get the cab, so unfortunately we've had to abandon the idea.
Hopefully there are more cabs out there that can be saved, but hopefully in better, and more safer locations
Thanks to Rob for putting in some effort on this
