In November 1989, in the Raniganj coalfields of West Bengal, a massive mining disaster occurred. 65 miners were trapped inside a flooded coal mine. While the world’s media moved on, one man stayed behind.
That man was Jaswant Singh Gill (played by Kumar), a Chief Mining Engineer with the Coal India Limited.
While everyone else discussed the impossibility of the rescue, Gill engineered a solution that had never been attempted before in India: creating a steel capsule (dubbed the "Gill Capsule") to extract men one by one through a narrow borehole. mission raniganj
This isn’t a fictional hero. He was a real civil servant who risked his career and his life to dig a tunnel to hope.
Gill personally supervised the drilling, refusing to leave the site. As water and mud spewed from the borehole — a sign they had hit the chamber — cheers erupted. But the real test began. Lowering the capsule into the unknown, with no visuals of the men below, was like sending a key into a lock in pitch darkness. In November 1989, in the Raniganj coalfields of
One by one, 64 miners were hauled up through that narrow steel tube — drenched, exhausted, but alive. Each trip took nearly 15 minutes. For two days, Gill coordinated every move, every signal, every heartbeat of the operation.
Here is where Mission Rananjigan becomes a story of jugaad (ingenuity) at an industrial scale. Gill had no factory. He had no blueprint. He had a borehole, a welding torch, and 40 hours. The welding was done in shifts
Working with the colliery’s mechanical staff, Gill designed an oblong steel cylinder—affectionately called the Gill Capsule or Bathyscaphe. Dimensions were critical: 2 feet 2 inches in diameter and 3 feet 9 inches in height. It looked like a small diving bell. It had a hinged lid, a small perspex window, a single lever for the trapped man to operate, and a valve for air circulation.
The capsule had to perform four impossible tasks:
The welding was done in shifts. The steel was salvaged from the mine workshop. There was no time for computer modeling. Gill used slide rules, instinct, and sheer courage.
