question:  What happened to cause panic during the communicaton between Freedom 19 and the Cape?
context: General Finogenov notified Major Winship that the underground blast was scheduled for the following morning. Major Winship, after receiving the message, discussed precautions with the three other Americans. Next morning, before the sunlight exploded, the four of them donned their space suits and went and sat outside the dome, waiting. "Help?" " Nyet ," said Major Winship, exhausting his Russian. "When?" "Boom—boom!" said Pinov. "He's done it deliberately," said Capt. Wilkins, the eldest of the four Americans. "Ah, it's all Russian. "I'll try again," Major Winship said and switched to the emergency channel. "Tell him, 'Help'," said Capt. Wilkins, "so he'll get somebody we can talk to." "Hell, Charlie, I feel stupid sitting out here," Capt. Lawler said. He crossed with the floating moon-motion to the airlock and entered, closing the door behind him. His foot was lifted for the second step when the floor beneath him rose and fell gently, pitching him forward, off balance. It then abated to something in excess of normal. Air currents whisked it away and plastered it against a riveted seam of the dome. It pulsed as though it were breathing and then it ruptured. Major Winship moved quickly to cut out the emergency air supply which had cut in automatically with the pressure drop. It's on your right side, midway up. Major Winship said, "they should have made these things more flexible." The sheet began slowly to slide downward, then it fell away completely and lay limply on the floor. Electrical cables trailed loosely along the walls and were festooned from the ceiling, radiating from the connections to the outside solar cells. After repeatedly assuring you there was no danger of a quake—and then to have something like this happen. "Just leave us alone, thank you," Major Winship said and cut off the communication. Capt. Lawler ascended.
