In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: Eric Stoltz plays John Dantley, an NTSB officer sent to O'Hare Airport in Chicago to investigate a collision between Global Airlines Flight 1025 (a Boeing 757-200 from Los Angeles to Washington D.C.) and PDO Cargo flight 342 (a Boeing 727-200F flying westbound cargo plane), where 185 people are killed.
Charles Martin Smith plays Henry Drake, an air traffic controller who insists his radar system malfunctioned when the planes were being cleared for landing. When the rest of air traffic control dismiss Drake and blame the incident on human error, Dantley must discover the truth about the crash: Was Drake — a high-strung individual who already didn't get along with his co-workers — simply incompetent at his job or did Drake's co-workers and superiors know about and/or had been previously been warned about the aging radar system showing signs of seriously malfunctioning and crashing at critical times (and thus liable to lead to deadly situations such as the one that happened), but instead of taking action ignored the warnings and initiated a cover-up?.
A:
What were the two flights that an NTSB officer was sent to O'Hare Airport to investigate a collision between?
