The majority of the emergency response group did not appear to arrive on site until more than 20 minutes after the crash - as can be seen in the amateur video of the incident.
What do you mean by the MAJORITY did not appear? First on the scene should be the fire trucks and if my memory serves me well, the amateur video shows the first fire trucks there in under five minutes.
I think questions need to be asked about why they failed to put out what appeared to be a small engine fire before it spread to the fuselage and at one point in that video we saw two fire trucks firing water right over the top of the fuselage at each other!
