All data is from FlightAware. Flights are regularly scheduled Boeing 777s into SFO.
This graph has a flaw: Notice that the X-axis is seconds until an arbitrary event (when the tracking ends), the fact that AAR214 on 7/6 is offset to the left does not correspond to physical location.
ADDENDUM: added chart of rate of descent. Working on getting the highlighting right...
