One of the things we've found in the mysterious underground facility under our base was a pile of technical documentation. It describes an attack helicopter that was being worked on by the 'UAC Corporation' in 2100s. The data is spotty and incomplete, but we can use it to design a massive upgrade to the Little Bird... once our technological capabilities reach the necessary level. We will need the capacity to work Plastasteel, the knowledge of Aerodynamics as well as an easy access to aircraft parts. There is also the issue of replacing the original, unknown fuel with something currently available but powerful enough. Finally, we need to have a chat with someone who knows enough about this sort of ancient technology...
