While there are always lessons to be learned from any incident, these types of incidents are almost always going to skew the capabilities and actions of emergency response personnel.
You cannot match victims with responders on a one-for-one ratio as people would desire. Response time to any victim always seems too slow regardless of the actual response time; just the nature of perception in an emergency situation.
Any emergency response is going to be overwhelmed initially to this type of situation until and IF an INITIAL adequate response plan can be implemented given the circumstances, equipment, and personnel available. The old adage; “you do the best you can with what you have at hand.”
It is not economically feasible or reasonable to staff airport fire departments with extra EMT/Paramedics and ambulances on a daily basis. These resources will always be placed out in other portions of the city/county that require their services on a daily basis (not yearly or even much longer on average at airports).
I have no dog in this fight and am not sure how good or bad the first responders performed in this incident. They are usually their own worst critics in the many post-incident reviews I have participated in. It can be a brutal review process for all involved.
