New Delhi: Amid the 360-degree rescue efforts by all agencies to save 41 workers trapped inside the collapsed Silkyara tunnel in Uttarkashi, Micro tunnelling expert Chris Cooper Tuesday said it was looking very positive as the rescuers were able to bore through 50 metres vertically with only 5-6 metres remaining.
In a video bite given to news agency ANI, Cooper asserted that they did not find any obstacle during the drilling on Monday night.
