I saw this thread title and thought "my goodness, they only have the one day to do all that"! Which reminded me of an old friend who had to go to North Korea many years ago to install diesel generators at an oil refinery that was being built on the waterlogged gravel of a river delta (bedrock? footings? health and safety?). On leaving the site one day all the contractors were told that there would be no work the following day. On enquiring as to the reason they were told that the day was set aside for the rice harvest. Lo and behold the next day the paddy fields were full of people harvesting rice, ready or not. At the end of the day what they got was what they got and the rest was left to moulder in the fields. I somehow don't think they power their rockets with any rice based bio fuel!
