NSIB's preliminary report on T7-SEI lines up with the pattern. Locking mechanisms found open. Internal and external handles both open. Door indicator showing UNLOCKED/RED.

That's a door that was never closed and locked, not a latch that failed in flight. There's nothing to log if the system never saw a secured door.

What I'd want answered is the pilots' report of no audible or visual warning when the indicator itself was red. Was it missed on the walkaround, or could it be a warning that didn't annunciate?

Glad everyone made it back safely. Just for some context though; if this happened shortly after takeoff, a true explosive decompression is unlikely because the cabin pressure differential is still low near the ground.

A documented cause on this type is a door not fully latched or locked before departure. A Challenger 601 lost its main door at about 3,000 ft in 2012 (N207JB) for exactly that reason. The crew diverted and landed without injury.

Not doubting the account, just the pattern. Looking forward to whatever the investigation finds.

Camera is mounted way up in the vertical stabilizer, the highest spot on the whole plane. That’s why you get such a clean, unobstructed view of the wings and runway.

It’s an optional add-on, not required for airworthiness. If it stops working, they just defer it under the MEL the same way they would any other IFE item.

Watch the wing right at touchdown. You’ll see the ground spoilers pop up before you even feel the plane settle in the cabin.
