Burrows Culham Laboratory, England iii/iv LAUNCHING INTO SPACE The National Interagency Coordination Group (NICG) extends you a cordial invitation to attentdh e 1991 International Aerospace and Ground Conference on Lightning and Static Electricity. Kennedy Space Center and Cape Canaveral Air Force Station are frequently called America’s Spaceport. This title is earned through the integration of many skills in a wide variety of technical fields and successful implementation throughout labor and management levels that enables America to reach into space. Among the many challenges confronting the country’s primary launch site are lightning protection, detecantd iforoecnast,ing . This conference focuses on studies that attempt to solve these problems by presenting papers on active research on many appropriate topics. The technical program for this year’s conference consists of 119 papers and posters presented by investigators from fifteen countries making this a truly international effort. The conference is divided into twenty-six sessions based on research in lightning, static electricity, modeling, and mapping. These sessions span the spectrum from basic science to engineering, concentrating on lightning prediction and detection and on safety for ground facilities, aircraft, and aerospace vehicles. There is something for everyone, whether student or veteran to the field. I invite you to come to the conference and participate with us, sharing what you have learned and your concerns.
