For those who aren't sure of the importance of this dig -
Search Will Follow 'Tried And Tested' Method
Updated: 7:35am UK, Monday 02 June 2014

The new searches in Praia Da Luz by police investigating the disappearance of Madeleine McCannn will follow tried and tested principles.
Former Metropolitan Police search adviser Keith Farquharson explained to Sky News how the teams will work to try to narrow down the search.
He said: "The investigation team will have done their background work on where they think their suspect will have gone once they had decamped from the scene.
"They will fit that around the profile of the most likely deposition sites for the body, if that is the case.
"They will involve a search adviser who will put together the search plan - then they advise the senior investigating officer that you need to fly over the areas that you want to search. Done - ed
"It will then be analysed to see if there is any ground disturbance or any anomalies from looking down from the air. Done = ed
"The area will be properly mapped with GPS coordinates for each one of those sites.
"Those areas will then be broken into smaller areas or chunks of land, which will be easier to search.
"Then you would send in the ground penetrating radar which will look for anomalies. Done - ed
"It will show anomalies within the earth structure but it won't show a skeleton like an X-ray would - it would just show the anomaly in the ground.
"So that would have to be investigated and the best way to do that initially is victim recovery dogs and the methods they use. Done - ed
"Once they have been through, if they don't find anything then it is decision time for the senior investigating officer - do they want all of those sites dug and physically searched? Yes, apparently they do - ed
"The searching can then be physically done by humans or digging machines can be brought in. Humans are digging today - ed
"When you have finished it, whether or not you have found a body or deposition site, you have got to be able to say hand on heart to the senior investigating officer either 'we have found what we have been looking for, and we have recovered it properly and we haven't compromised any evidence'.
"Or, 'we haven't found it and it definitely isn't there,' which is almost as useful because you are discounting part of that land from that part of the investigation."
The dig would NOT be proceeding UNLESS both the cadaver dogs have alerted, AND GPR indicated something "substantial" as we have already been told.
