Physical Evidence Related to UFO Reports: the Sturrock panel (Pocantico workshop, 1997; report 1998)
Also known as Sturrock panel, Sturrock report, Pocantico workshop, Rockefeller UFO workshop
The Sturrock panel was a scientific review of physical evidence in UFO reports, held as a workshop at the Pocantico Conference Center in Tarrytown, New York, from 29 September to 4 October 1997. Laurance S. Rockefeller's LSR Fund paid for it, the Society for Scientific Exploration administered it, and the Stanford physicist Peter Sturrock directed it. Eight investigators presented photographs, radar cases, vehicle and aircraft interference, ground traces, injuries and the Hessdalen measurements to a panel of nine scientists. It was not a government inquiry.
The panel found no convincing evidence of unknown physical processes or of extraterrestrial intelligence. A few cases might involve rare electrical phenomena such as sprites, or radar ducting, and a few might come from secret military activity. Further analysis of the evidence presented was unlikely to settle the cause of the reports. It still judged that careful, objective study of new physical data could teach something, and named the French GEPAN/SEPRA office as a model.
The report appeared in the Journal of Scientific Exploration 12(2) in 1998, with the investigators' presentations, the panel's comments and appendices on GEPAN/SEPRA, ducting, sprites and scientific inference. Our copy is a reproduction of the journal's web edition.

Facts and claims
- documented The workshop was held at the Pocantico Conference Center, Tarrytown, New York, from 29 September to 4 October 1997, organised by the Society for Scientific Exploration in response to an inquiry from Laurance S. Rockefeller, chairman of the LSR Fund, which paid for it. Its director was Peter A. Sturrock, professor of applied physics at Stanford University. The report was published in the Journal of Scientific Exploration 12(2), 1998. Source: doc-sturrock-panel-1998.pdf
- documented Eight investigators (among them Richard Haines, Jacques Vallee, Erling Strand of Project Hessdalen and Jean-Jacques Velasco of CNES) presented their strongest physical evidence to a review panel of nine scientists, co-chaired by Von R. Eshleman of Stanford and Thomas E. Holzer of the National Center for Atmospheric Research. Source: doc-sturrock-panel-1998.pdf
- documented The panel's finding: a few incidents may have involved rare but significant phenomena such as electrical activity, “but there was no convincing evidence pointing to unknown physical processes or to the involvement of extraterrestrial intelligence”. It adds: “A few cases may have their origins in secret military activities.” Source: doc-sturrock-panel-1998.pdf
- documented It concluded that “further analysis of the evidence presented at the workshop is unlikely to elucidate the cause or causes of the reports”, but that new data, scientifically acquired and analysed, especially of well-documented recurrent events, could be useful, and that UFO reports deserve careful evaluation with objectivity and a willingness to weigh rival hypotheses.

- documented It held up the GEPAN/SEPRA project of the French space agency CNES as “a valuable model for a modest but effective organization for collecting and analyzing UFO observations and related data”, and, citing evidence that some witnesses had suffered radiation-type injuries, drew the medical community's attention to a possible health risk.
