Grand Theft Auto 5 (GTA 5) is set in the picturesque city of Los Santos, which is part of the fictional state of San Andreas from GTA 4. Despite the locale inheritance, GTA 5 does not feature the jet pack item found in GTA: San Andreas.

Several GTA fans have been eagerly expecting Rockstar to feature the jet pack item in its upcoming DLC for GTA 5. According to a recent post on Kotaku, some discerning gamers have already uncovered a few hidden Easter eggs pertaining to the jet pack in the game's campaign mode.

One such Easter egg points to a mysterious sign printed on Trevor's hangar that reads "Jack Sheepe Servicing-Tri Manifold" that also carries the code "R-108" below. It is ascertained by The Daily Dot that the sign depicts an anagram deciphered as "Jet Pack Confirmed".

Besides, "Jack Sheepe" is the stage name of a porn star called Jake Steed who featured in the remake of the movie, The Rocketeer. Quite strangely, The Rocketeer also features a jet pack with a run time of 108 minutes.
