Season overview

Task: Write a JSON object for "Air Disasters" Season 20.
Keys: overview (160-220 words), primer (array of exactly 4 concise bullet points).
Constraints: Use only the provided synopsis and sources. No invented facts. No markdown. No asterisks. No headings. No bullet points in the overview (plain text). No markdown in the JSON.
Input: TMDB Synopsis and Sources [1, 2, 3, 4].

Problem: The provided sources do not contain any information specific to "Season 20". They describe the general series "Air Disasters".
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Consequence: Since there is no information about Season 20's specific narrative arc or specific previous lore/stakes for that season in the text, I cannot fulfill the word count requirement for the overview (160-220 words) without inventing facts. However, I must provide a JSON object.
Wait: If I cannot fulfill the specific requirements (160-220 words) because the data isn't there, I must look at what I can say about the series based on the text provided.
Refined Strategy: The prompt asks for Season 20. The sources describe the series. I will describe the series' premise as the "narrative arc" of the show's content, but I cannot provide a specific arc
