searching the wiki, the thunderbolt is referenced (linked to) on several pages already - among others, in the "military aircraft" category:
http://wiki.flightgear.org/Category:Military_aircraftThat said, I tend to agree that it would definitely make sense to optimize this a little and improve it such that a navigation bar is displayed for things like aircraft, i.e.:
Aircraft / Military Aircraft / Jet
It's all perfectly doable with the wiki, i.e. by creating a new template.
Please let me know if you have a better idea
