Boimler's PADD showing the cover of Fleet
Fleet was a periodical described as "The Official Starfleet Magazine."
In 2382, Brad Boimler was interviewed by Fleet after he had captained the USS Cerritos and expected to be featured in the publication's "30 Under 30" feature (Issue #47). To his disappointment, his photo and article were not included, despite Naomi Wildman and fourteen others having received honorable mention.
The cover of that issue also referenced the top ten "Riker Moments", "Q Who? The Continuum Awaits", and "Klingon Kouture: Blood is the New Black." The magazine also touched on topics such as discoveries, tributes, and Trekonomics. (LD: "Dos Cerritos")
The placement of "The Official Starfleet Magazine" on the cover is likely a reference to Star Trek Magazine, which featured a similarly positioned "The Official Monthly Magazine" on early issues.
