October 29, 1999 My wife and I decided to move our family to Arizona. I still liked my NASA job and wanted to keep doing it. My supervisor and I worked out an arrangement where I could telecommute. My 4 year old son and I drove down from San Jose to Phoenix. Our car was mostly stuffed with my computer equipment. Even though we were traveling in June, we actually got caught in a snowstorm when we were driving over the Sierra's. My chains, of course, were in the back corner of my trunk and I would have had to take all the computer stuff out to get them. Luckily, I went over the pass just before the Highway Patrol was going to close the road so we made it. I've set up one of the rooms in our house to be my office. I couldn't bring down all of my stuff, but I brought down quite a bit. I have a Mac, a workstation, a printer, and a scanner. I filled up the closet with all of my papers. A typical work day goes like this. I take my children to daycare and then come home and log in to the NASA computer systems. I do this by dialing in to a NASA machine with my modem. Once I'm connected, I can do almost everything I used to do. I check my computer jobs, analyze data, sometimes I participate in teleconferences. The only thing that is not so good is that I was so used to the high-speed communication lines at NASA that my 56K modem seems really slow. I really like telecommuting and hope I can keep doing it. The initial deal was for six months. I'm trying to get an extension right now, so I can keep contributing to the Space Technology programs at NASA.

"AVIATION DREAMING" an excerpt
by Daniel S. Goldin
October 19, 1999 ...In a few decades - with aggressive, visionary, and bold investments -- we could put together all the technical achievements in safety, noise, emissions, capacity, cost, and revolutionary designs. We could produce a seamless transportation system with tremendous "doorstep to destination" speeds. What might such a system look like? Let me take you on a little journey. A husband and wife and their two children are headed home to Pigeon Forge, Tennessee--in the heart of the Smokey Mountains--after taking their oldest daughter to Chico, California, where she is starting college. The wife is a military aircraft design engineer for a West Coast firm. Next-generation fully immersive collaborative computer environment technologies, like NASA's Intelligent Synthesis Environment (ISE), let her work with the design team even though they live thousands of miles apart. This family came into the San Francisco Airport from Chico on a new Runway Independent Aircraft, an advanced version of the V22 Tiltrotor. They were a little disappointed, because they really wanted to try out the new STOVL aircraft just completing certification. It has morphing, mission-adaptive wings, derived from technologies NASA began working on back in 1999. At SFO, they board a modern, quiet, low emission transport aircraft that has just completed a self-check of its structures and flight systems and certified itself "ready to fly" by using its integrated vehicle health management system. As they push away from the gate, the fog is thick and visibility is low, but safety is not affected and the flight will not be delayed. The crew is using the advanced taxiway and runway navigation and visualization tools developed by NASA and the FAA. A computer that efficiently manages planes on the ground and in the air clears the pilot for takeoff. Enroute to Chicago O'Hare, the family uses the integrated communication system to confirm their rental jet. They are looking forward to the one-hour shuttle jet ride to Pigeon Forge because they can stop in Kentucky to see relatives if they want. They have that luxury, because their door-step-to-destination time has been cut by a factor of four. In Chicago, they get off the plane . . . and follow the signs to the Hertz Rent-A-Jet counter. The family confidently boards their rental jet . . . the days when General Aviation airplanes were a factor of 10 less safe than scheduled airplanes have long passed. In fact, they pre-flew this trip during the flight to Chicago, using their laptop. The simulation included real-time updates, optimized route planning, and it assures the family's safety when they make the actual flight. The trip is surprisingly inexpensive. As a matter of fact, thanks to the advances we spoke about earlier, the price of all airplanes has come down dramatically. Both the husband and wife can fly . . . because years ago, their employers saw the advantage of personal air transportation to business . . . and knew that with personal air travel they could accomplish in one day what used to take 3 or 4 days back in 1999. Their middle child is 15. Next year he will enroll in "Flyer's Ed" at school. The rental jet is equipped with intelligent avionics . . . and the family cannot even fathom that there was a time when people didn't have real-time, on-board assessment of aircraft health, local atmospheric conditions, artificial vision, and air traffic. They pity pilots in the "aviation Middle-Ages" -- the 1990's. In 2020, controlled flight into terrain and weather hazards are no longer major causes of accidents, and general aviation will never again take a back seat in safety. Unlike the old days in 1999, the pilot's route is nearly a straight line because of the Free Flight capabilities developed by NASA and the FAA. The "Smart Airport" system provides excellent separation and sequencing of aircraft, even without control towers or radar, and an "Airborne Internet" provides real-time weather, traffic, and landing facility data. With these new systems pilots avoid constant flight path re-vectoring-- saving fuel and time, while increasing safety and reliability. The plane slips quietly and cleanly through the air. It is much quieter outside the plane and inside the plane for passenger comfort. Engines are quieter, and smart airframe and interior wall structures actively cancel out most of the noise that would otherwise be heard and felt in the cabin, eliminating travel-induced fatigue. The plane's 3-D, multi-media communications environment allows them to virtually visit their Kentucky relatives. During the conversation, they smell the turkey cooking and are invited to stop for dinner. They leave their rental jet at a small unattended "Smart Airport" in eastern Kentucky where their relatives are waiting to pick them up. After dinner with their relatives, the family takes a cab to the airport. And after a short plane ride to Pigeon Forge, they are home in time for bed. A bold vision? Sure. Can we get there? Absolutely. We just have to work together with the same goal in mind--air flight anywhere, anytime, by anyone. With increased safety and increased reliability, even as capacity skyrockets. That will enhance people's quality of life and it will energize the aviation industry like nothing ever has. ..... The full text is available at ftp://ftp.hq.nasa.gov/pub/pao/Goldin/99text/WAC.txt
