team 1 proceeded to their target, three distilling towers, but were unable to lay their explosive in the right position as the design of the first tower and a manned control station did not match the intelligence so the explosives were laid on pipes into the tower. signalling the rest of the teams to begin their arming they proceeded to the second tower that appeared unmanned and out of commission. while attempting to break into the tower they were interrupted by a premature explosion from within the refinery at team 4's site. they then armed and left the charges at the towers' base and returned to the entrance site.
