While watching Macross 7 I noticed another homage from Macross Frontier to the Macross 7 Series. In episode 6 of Macross Frontier, Sheryl Nome gives protagonist Alto Saotome one half of her earrings to use as a lucky charm during their first battle with the Vajra. He hangs it in the windshield of his VF-25 Messiah.

Not sure if my eyes are failing me, but did YF-21 test pilot, Guld Goa Bowman just make a cameo in Macross 7?
