T-50，嗯是個蠻有趣的Case。

Partnership

看看LM怎麼說：

Korea Aerospace Industries (KAI), prime contractor for the program, is responsible for aircraft design, integration and major component fabrication and will mate and deliver the T-50 from their factory in Sacheon.

所以，KAI是T-50的主合約商。

Lockheed Martin Aeronautics, principal subcontractor and advisor to KAI for the development program, is responsible for the development of the wings, flight controls and avionics. Lockheed Martin is also partnered with KAI for long-term marketing the aircraft in the U.S. and internationally.

LM則是次合約商與顧問，但LM卻控制了這架飛機的'靈魂'。(當然老美給控制了這架飛機的'心臟'。)

雖說KAI負責飛機設計與系統整合，但沒有機翼設計算是飛機設計嗎？飛控與航電KAI都不准碰算是系統整合嗎？

當年LM建議KAI來台找AIDC幫忙，不是LM說了KAI就買單，KAI也是派人來台確認AIDC夠格後，才答應找AIDC，當時也確實有批工程師要到KAI幫忙，可惜因某些原故，最後沒有成行。後來才有離職的幾個員工跑到KAI工作，所以，網路才會有傳言。
