In 1983, Betty Hamilton, onetime chief stewardess on Steve Burton's old flight crew, testified before a Congressional science sub-committee concerning her experiences with the time-space rift described by Alexander B. Fitzhugh in his account of the so-called "land of giants" incident.

Giant Surprise Part 6Ms. Hamilton's testimony gave further insight into the nature of the rift and was used as a guide for writing the mission profile for the first manned flight of Project Spindrift.

A transcript of the hearing was subsequently forwarded to European Space Agency director Jason Webb, who flew to Cape Canaveral a week later for further debriefing. Webb would eventually come to be more closely associated with Project Spindrift than anyone other than Burton or Fitzhugh.
