The codename for the Macross bridge is Gunsight One. Gunsight One was a Gundam fan club founded by some of the staff members (such as creator Shoji Kawamori and character designer Haruhiko Mikimoto), mecha and anime fanatics on their own right.
The names of the Zentradi spies Warera, Rori and Konda form a complete sentence in Japanese. When rendered into Japanese words, this comes out as "Warera rorikon da". In English, the sentence means "We're pedophiles".
When the AnimEigo DVD release was being prepared for release in the United States, there was serious discussion of adding a Zentraedi language track as a bonus. The idea was scrapped.
Among other production headaches, the master copy of one nearly-completed episode was reportedly accidentally left on a train by a courier, forcing the staff to search for the footage - otherwise they would have to reanimate all this, at a considerable cost in time and money. They found the reel, and so disaster was averted.
There were plans for a splashy ending to the series, one that would have shown Misa and Hikaru blasting off in the colonization ship Megaroad, but the sequence was scrapped due to lack of time and budget.
