What is "the aerodynamics of a brick"?
Native speaker’s answer
Rebecca
The speaker is being sarcastic and humorous here. A brick is heavy, clunky, and does not have good aerodynamics, so the speaker is comparing the plane to a brick here. He is implying that the plane is not very aerodynamic and even mentions earlier that it does not fly very fast either. Because the flight is short and does not carry many passengers at a time, the plane is not very sophisticated or high-tech.
