repaired. At 8:58p.m. the repairs were completed on the No. 1 drill air lock and drilling resumed. At 10p.m. the water elevation was 1827.92 mean sea level (MSL). The No. 1 drill cut through into the mine at 10:16p.m. at a depth of , which was then lower than the elevation of the mine’s portal. Drilling of a second escape hole had also been underway, in case one was needed. At 7a.m. on July 27, this hole was at a depth of when drilling became very hard, and at 1:31p.m. the No. 2 drill lost its bit, hammer, and reamer in the borehole at approximately . Repairs were being made when Rescue Hole No. 1 broke through into the mine, and drilling then ceased. Rescue After Rescue Hole No. 1 broke through into the mine, rescuers signaled the trapped miners by tapping on the drill steel with a hammer, and a faint response was heard. The miners had been taking turns walking every 10 or 15 minutes down the passageway from their high ground location to check the area where the drilling sounds were coming from. When Hileman and Foy made the trek on Saturday at about 10:15p.m. their cap lamps were dim, but that is when they found the drill opening and Hileman alerted the others. Immediately after the rescue hole penetrated the mine, all equipment was shut down in order to take an accurate relative air pressure reading between the mine and surface atmospheres. The pressure reading was zero, indicating that the pressures were equal and that the airlock would not be required. The compressor was turned off and the drill steels were removed from the hole. At 10:53p.m. a special pen-shaped, two-way communication device was lowered into the 6-inch air pipe, with a child's glow stick attached to it for visibility in the dark mine. Communication was established with the miners who confirmed that all nine were alive and well, except for the foreman who was experiencing chest pains. At 12:30a.m. on July 28, the 8½-foot high steel mesh escape capsule, with supplies, descended into Rescue Hole No. 1, into the void where the men had languished in fear and hope for 77 hours. Due to recurring chest pains, foreman Randy Fogle was chosen to be the first rescued miner, and arrived on the surface at approximately 1:00a.m. The removal order of the rest of the crew
