Cortana, all I need to know is did we lose them.

@SW-User It's a line from the very first Halo video game. In fact, it's the first line of dialogue of the entire game, making it the first sentence spoken in the whole series.

Cortana is the onboard AI of the military spacecraft Pillar of Autumn and captain Jacob Keyes is asking if they've managed to outrun the aliens they're fleeing from.

Fun fact, Cortana the Windows assistant is named after Cortana from Halo. The games were made for Xbox, which is produced by Microsoft, the same company that makes Windows.

@BlueMetalChick Fun fact, thank you.

@Doometernal She's a character from Halo.
