Honestly, I say scrap the coaster idea entirely, and just do the new revamped "enterprise" flat ride instead.. it'd make more sense with the "First Flight" title.
^This version is a 2-seater to double capacity.
If they painted it black with green, it'd look great. Plus the glowing green lighting package at night would look great in DC Universe (something Flash & Wonder Woman could seriously benefit from getting during those nighttime operations)
