time of response...
Looking at the video, I guess it must have taken the person who took the film at least 60 seconds to leave the plane, get to the edge of the runway and then start filming, yet at the end of the video clip (a further 56 seconds), there still appears to be absolutely no sign of rescue services.
Sadly - from experience - this doesn't surprise me. But as a resident in Thailand and someone who flies very frequently, I find this apparently tardy response rather alarming.
