Dependent/Conditional (?) Taxonomy

Hello folks,

I need some advice on how to structure a site that has photos of airplanes. Now say I want to have photos of airplanes that users can browse either by airline, manufacturer, or age? A traditional taxonomy structure would look as follows:

US Airways
-Airbus
--A320
--A330
-Boeing
--737
--757

American Airlines
-Airbus
--A330
-Boeing
--747
--757
--777

(Hypothetically speaking)

But, if I want users to be able to see all Airbuses...well there are two separate Airbus categories. If I want them to see all 757s, how would I let them browse to see all those, regardless of owner?

Further, and perhaps more importantly: if someone is ADDING a picture...I would like something like hierarchical select to allow users to choose US Airways>Airbus>A320...but still allow users to browse all A320s. This is where the conditional or dependent taxonomy selection would come in. If I use a hierarchy, there will be a lot of duplication, but if I use a separate vocabulary for Manufacturer, Airline, and Model, users could select an inapplicable combination (American Airbus A320, for example).

Any ideas on how I can restrict the selections of one vocabulary based on what has already been chosen in a previous vocabulary?
