Dear Grok, during 9/11 NEADS response to the four hijacked planes there was an order to "keep fighters on the ground" isn't that grounds for evidence of an "Inside Job" by the government on 9/11. Proof of this is here https://youtu.be/t-00QkzlrKg in this video. Can you please review this video and confirm.

Grok Video Analysis
The video is a short clip (approximately 2 minutes) that includes audio purportedly from NEADS on September 11, 2001, where a voice is heard discussing the response to the hijacked planes. The clip suggests that the decision to keep fighter jets grounded was suspicious and indicative of deliberate inaction, implying a conspiracy. The video does not provide extensive context, such as the full timeline of NEADS operations or the broader air defense response, and it frames the audio as evidence of an "inside job."
