You ever done a Lander drop before? Hello. This is a line from Alien Covenant (an American sci-fi movie, 2017) my friend asked my help with, but I have no idea either. The context as follows: The spaceship Covenant decides to send a lander to an Earth-like planet. As the expedition team is boarding the lander: Man: Hey, you ever done a Lander drop before? Woman: F**k you. Sounds like there's an element of sexual innuendo in this short banter. If so could you explain it, please? Because I see nothing beyond the literal meaning.
