“The longest the feeler can be at present is ten meters. Any longer and it won’t be strong enough. But, for your purposes, there’s no strength requirement for contact, and your speed requirements might be one to two orders of magnitude less than ours. In my crude estimation, the feeler could be as long as twenty-five meters. But there’s one more thing: it can carry the superconducting lead you need, but apart from that you can’t affix anything to the tip.”
Lin Yun nodded. “That’s basically enough.”
On the way back, I asked her, “Do you really intend to do it? Isn’t that betting too much on Ding Yi?”
“We’ve got to give it a try. I think Ding Yi really is the person to make a breakthrough in ball lightning research. We’ve said before that this mystery won’t yield to conventional thinking. Now we’ve got some unconventional thinking, but you won’t accept it.”
“The problem now is how to convince Colonel Xu and the aviators.”
Lin Yun sighed softly. “If only I knew how to fly a helicopter.”
Back at the base, Lin Yun described her plan in a hastily convened meeting.
“You want to poke a thunderball with a long pole? Are you insane, Major?” Captain Zheng said loudly.
“Once again, the pole isn’t going to touch a thunderball in an excited state. It will touch the bubble that may possibly exist in that position the instant the thunderball goes out.”
“Professor Ding said that the superconducting lead carried on the pole must reach that location within half a second of the thunderball going out, otherwise the bubble will blow away. Is that level of precision possible? What if it’s half a second too early?”
“The reaction time of the feeler defense system is faster than our requirements by two orders of magnitude, although that’s for the original system’s feeler, which moves when the target appears at a specified location. In our improved system, the feeler moves when the target disappears. And our previous observations of EM radiation and visible light have given us data for a precise determination of the ball lightning’s disappearance.”
“Even if you can do all that, the helicopter still needs to be twenty-five meters from the thunderball. That’s half the distance of the last time there was an accident. You’ve got to be aware of the danger involved.”
“I am aware, Captain. But it’s a risk we must take.”
“I don’t agree with the plan,” Colonel Xu said, with a tone of finality.
“Colonel, even if you agreed, we wouldn’t fly this mission,” Captain Liu said. “The two crews are only on loan to the base. Ultimate command authority rests with the army group. We have the power to refuse any command that endangers the safety of the group. Our division leaders reemphasized this point after the last accident.”
Lin Yun appeared unfazed. “Captain Liu, if you received a command from the army group ordering you to undertake this mission, would you carry it out?”
“That would change things. Of course we’d carry it out.”
“Could I get a guarantee of that?” she said, not moving her eyes from Captain Liu. Her expression frightened me.
“I guarantee it in my capacity as officer in charge of the helicopter group. But, Major, the army group won’t give that order.”
Lin Yun said nothing. She picked up a phone and dialed. “Hello, I’d like to speak with Senior Colonel Zeng Yuanping…. This is Base B436. Yes. That’s me. Yes. Thank you!” She passed the phone to Captain Liu. “Captain, the Eighty-Second Aviation Brigade Commander of the Thirty-Eighth Group Army is on the line.”
Captain Liu took up the phone. “Speaking…. Yes, Commander. I understand…. Yes. Certainly!” He put the phone down without looking at Lin Yun. Then he turned to Colonel Xu. “Colonel, we have received orders to fly this mission. The time and number of flights are to be determined by the base.”
“No, Captain Liu. Please inform your superior officer that until reliable safety measures are found, the base is halting all observation flights,” Colonel Xu said emphatically.
Phone in hand, the captain hesitated, glancing at Lin Yun. Everyone was looking at her.
Lin Yun bit her lip and remained silent for several seconds, then reached for the captain’s phone, hung up, and dialed another number. “Hello, sir? This is Base B436. Yes, it’s me. About the report I made yesterday…. I’d like to know whether the higher-ups have…. Good.” She passed the phone to Colonel Xu. “Deputy director of the GAD.”
Colonel Xu took the phone and listened grimly. He finally uttered two words—“Yes, sir”—and put the phone down. Then he turned to us and said gravely, “The higher-ups have ordered us to proceed with the experiments to capture unexcited ball lightning according to Major Lin Yun’s plan. In addition, they have ordered that all other work at the base be suspended so that our energy can be focused on this experiment, and they expect everyone to dedicate themselves to the work in their respective capacities. Would the technical directors for the projects please stay behind after the meeting?”
