Ok listen up, we have to lower supplies down this narrow ventilation shaft to keep the miners alive. We also need a ventilation pump set up to force fresh air down this shaft. Meanwhile the drill crew is going to drill the larger rescue shaft down from the adjacent hilltop to bring the miners out one by one. We have 24 hours at the most to get this done before someone down there poops and kills everyone and this ends in tragedy !
