It was listed for next Monday but not now it seems. I've mailed the production company for info, they sent me a copy some weeks ago, although it covers some of the same ground as the Channel 5 programme it really is worth watching if only for the footage of the people of West Sumba moving a stone on rollers.
600 people to move a stone of perhaps 15tons (my estimate) a grand total of 100yds in a full day, and these people are experts. I'm more convinced than ever that the sarsens at Stonehenge were not pulled along on rollers.
