Enterprise's First Flight: A Pivotal Moment

  • August 12th, 1977: Fred Hayes Jr. and Gordon Fullerton prepared for Enterprise's first flight off a modified 747, aiming to land on a dry lakebed 15,000 feet below.
  • Concerns centered on reaching launch speed and separating from the 747 smoothly, ensuring no collision.
  • Pilots Fitz Fulton and Tom McMerkin awaited the command to release the 747 from under Enterprise.
  • Successful separation was confirmed by the absence of a collision, marking a pivotal moment in the test.
  • Five weeks later, Enterprise underwent a second freefall test with pilots Joe Engel and Dick Truly.
  • The test aimed to capture flight data accurately, requiring precise maneuvers and data points.
  • Columbia, NASA's first orbiter, faced challenges in weight reduction and tile attachment.
  • Columbia's thermal protection system, comprising over 25,000 tiles, posed significant engineering hurdles.
  • Shuttle tiles, designed to withstand extreme temperatures, were lightweight and composed of 90% air.
  • The astronaut selection process in 1978 marked a significant shift, welcoming diverse candidates from various backgrounds.
