Amazon Prime (Atlas Cargo) 767 down

It went from 5,850 to 1,325 feet, the last position captured by the website, in about nine seconds, which is many times faster than a normal descent rate.

Yikes! 4525/9 = 502.7 ft/sec. That's a bit over 30,000 feet per minute.

Now that's not off the FDR; that's "according to a flight plot provided by tracker FlightRadar24".

I'm finding it a bit hard to believe. That flight plot may have issues.

I am sure the instruments were not designed to eve see the type of descent that occurred. They probably went on the momo.

Preliminary CVR leak consistent with loss of control.   This video is chilling.

No doubt, the black box will be quite revealing.  The one video that shows the jet in a steep, rapid descent looks similar to a procedural loss of pressurization emergency descent from high altitude.

Yeah, but they weren’t that high when they started diving.

I believe they we 40 miles out @ an altitude of about 12k on final approach to IAH Runway 26L. Me and my wife had just driven past Anahauc as this happened. Did not see the plane as we were farther North driving on I-10 but saw multiple emergency vehicles on I-10 heading towards Anahauc. Went Duck hunting several times this past year where it crashed.

NTSB release.

Important bit:

"Also, about this time, the FDR data indicated that some small vertical accelerations consistent with the airplane entering turbulence. Shortly after, when the airplane’s indicated airspeed was steady about 230 knots, the engines increased to maximum thrust, and the airplane pitch increased to about 4° nose up. The airplane then pitched nose down over the next 18 seconds to about 49° in response to nose-down elevator deflection. The stall warning (stick shaker) did not activate.

FDR, radar, and ADS-B data indicated that the airplane entered a rapid descent on a heading of 270°, reaching an airspeed of about 430 knots. A security camera video (figure 4) captured the airplane in a steep, generally wings-level attitude until impact with the swamp. FDR data indicated that the airplane gradually pitched up to about 20 degrees nose down during the descent."

Aloha Snackbar Demo?

Aloha Snackbar Demo?

At this point, it's as valid of theory as any.

Be interesting whether they know yet if the full throttle and elevator pitch down were commanded or not.
