Flight Log (1966–1976) is a compilation album by the American rock band Jefferson Airplane. Released in January 1977 as a double-LP as Grunt CYL2-1255, it is a compilation of Jefferson Airplane and Airplane-related tracks, including tracks by Jefferson Starship and Hot Tuna, as well as solo tracks by Paul Kantner, Grace Slick, and Jorma Kaukonen. Although primarily a compilation album, the album includes one previously unreleased song: "Please Come Back" written by Ron Nagle and performed by Jefferson Starship. "Please Come Back" is not available on any other release.
The album included a lavish 12-page full-color, full-size (12 sq.in.) booklet, containing photographs of the band throughout the period covered by the compilation. It also contained a detailed history of the band, written by Patrick Snyder of Rolling Stone magazine.
Flight Log was first reissued on CD by BMG Japan on October 22, 2008, as a part of the "Paper Sleeve Collection" reissue series (BVCM-35468-9). The release features an exact reproduction of the Grunt 1977 edition of the LP packaging including a reduced scale reproduction of the original booklet and inner sleeve jackets for the CDs. Also included is a second booklet containing all the lyrics in both English and Japanese. The only omission by BMG Japan was not reproducing the original GRUNT label on the CDs. The audio quality is as good as the original master tapes available for the Japanese LP pressing and features JVC K2 24 Bit Remastering. However, it sounds as if the master tapes had been damaged on at least three songs, and significantly obvious on the introduction of "Silver Spoon". CD 1 contains Side A and B, and CD 2 contains Side C and D.
On April 5, 2011, BGO Records released a remastered edition of Flight Log in a standard jewel case with cardboard slip cover. The BGO version is said to be a sonic improvement on the BMG/Sony edition; nonetheless, certain tape defects such as on Silver Spoon still exist.
