The airplane industry precedent is a good one, but in this case you do have a professional cadre who work on investigating plane crashes, not making planes. This is because there are (or at least were) enough plane crashes to persuade governments to pay for this. As plane crashes have gotten rarer, the ability of the government (in the US, anyway) to maintain in-house expertise sufficient for the job, has declined, I think not coincidentally. Not sure what the solution is for airlines, but in any case for virus outbreaks we have (fortunately) too few cases to maintain an independent profession of investigators (I hope I am not naive in saying this).
