Through all of our challenges, we were aware of at least some of the incredible variety of positive and negative world events in the news—the bombings and the peace talks, the sports contests and the religious controversies, the national strikes and the latest developments in the arts. Amid the economic difficulties in our own country, and after a number of often very expensive delays, the second flight of our shuttle spacecraft, Columbia, came due on November 4. Of primary importance was to be the testing in space of the 50-foot-long remote-control robot arm, which had been designed to place satellites in orbit and retrieve them for service and repair. Only seconds before lift-off, however, computers shut down Columbia’s flight because of a drop in pressure in oxygen tanks. Then clogged oil filters were discovered. The launch was rescheduled for November 12.

There are plenty of more immediate challenges. For example: The staff of the Nuclear Regulatory Commission has asked the operators of more than 40 nuclear plants to check for cracks in the walls of the vessels encasing their pressurized-water reactors (which are the kind installed at TMI). Evidence is accumulating that the vessels are becoming embrittled by neutron radiation from the reactors much more quickly than their designers had anticipated. Small cracks have been found, but not all areas are reachable for testing. A rupture of a typical pressure vessel could result in an uncontrollable release of radiation into a containment building not designed to handle such a situation. If the building itself was breached, the escaping radiation could cause some 48,000 deaths, 250,000 nonfatal cancers and injuries, 5,000 first-generation birth defects, render 200 square miles uninhabitable, require decontamination of another 3,200 square miles, and damage other properties worth many billions of dollars. No protection against that kind of accident has ever been required by the NRC. The forces of consciousness at work would seem to be incredible—beyond our grasp.

We always liked the idea, however, that others were recording class events and were keeping tapes for us if and when we wanted them; we also liked the idea that it was safer to have the tapes scattered about instead of being kept in one place. In class Jane might have listened to portions of a tape as it was being made, or immediately after class was over, but seldom would I hear her playing the same tape later—if we had a copy of it, that is. She’s fascinated to hear herself speak as Seth, and sing in Sumari, but she always wants to move on. I simply have never devoted myself to collecting tapes. I don’t want to overstate the issue, but neither does Jane pay that much attention to a book once it has been published. She does reread various private sessions, usually those in which Seth discusses matters relating to her symptoms. Until this year (1981) she would occasionally replay one of the few tapes we’d made together, or use our recorder when writing poetry. She gradually gave up working that way, however, as it became more and more difficult for her to exert enough finger pressure on the recorder’s keys.
