Why did they not divert to KDAB, KMCO. KJAX. All within spitting distance and all with over 10000 feet runways.
Because either the Captain was of the opinion that it wasn't going to be a problem, or the company isn't very supportive of crews who elect to divert (due to costs). Personally, I'd go for the former. But it's all guesswork. How many times does the question "why did they not divert" come up after an accident?
