Can you customize flying vehicles in gta v story mode?

The only source supplied is a Wikipedia article about Grand Theft Auto Online, which describes the online multiplayer component of Grand Theft Auto V. It notes that players can control a customizable silent vehicle in the online game, but it does not discuss any customization options for flying vehicles in the story mode of GTA V. Because the evidence does not mention story‑mode customization at all, we cannot confirm that such customization exists there. In contrast, GTA Online offers extensive vehicle customization, including upgrades and skins for aircraft, but this is separate from the single‑player story experience.
