Notes

  • The Pelican was Boeing Phantom Works' 2002 study for an ultra-large cargo aircraft that would cruise in ground effect over water.
  • Only a 122 × 152.4 m plan-view envelope is modelled because overall height is not published. Figures are from magazine sources via Wikipedia.
  • Marked secondary.
  • True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
  • Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
