Uncountable nouns in resource routes with Rails 3

I have a model called Aircraft, inflected as uncountable, and it’s
driving me nuts. What is the correct way to handle this in Rails 3 beta
4?

resources :aircraft do
  member do
    get :flights
  end
end

# Of course these work for some actions and not others.
match 'aircraft', :to => 'aircraft#index', :as => :aircraft
match 'aircraft/:id', :to => 'aircraft#show', :as =>

:aircraft_instance
