Above is a link to the noise monitoring data at Essendon airport. The archive includes the accident date.
I note that the tracks of some aircraft appear at the beginning of the taxi or a hover.
Other tracks don't appear until the flight is past the end of the runway.
What method is used to derive the track? Why does the position of the commencement of the track vary between aircraft/flights?
There is no track for the King Air, it seems to fit the category of tracking that does not commence until the flight is past the end of the runway.
The decibel level of both the impact and post impact noises (explosions?) are recorded.

You refer to the ADSB tracking? Some systems transmit ADSB data as soon as they're turned on, others are interconnected through a squat switch or an air switch and don't transmit till the aircraft is going fast enough or the undercarriage extends fully.
