So what if this is the real Macross, and the one they have on earth is the sister ship?
so, crazy fanboy talk... what if a distraught global takes the SDF-1 out on a search for the missing Megaroad? When it goes missing as well, the UN SPACEY makes a replacement and has it come back, fearful of the negative PR of not only losing the megaroad but the Macross as well?
