The ACARS messages, the previous repairs, happen all the time.
''Uplink-PLEASE ADVICE ME
So what was Capt. Renslow asking about? The best place to get pizza in Buffalo? I think when the pilot sends a text message to base asking for advise right before a fatal crash, it might be relevant. I wonder why they never released the test of his message.
Turbine engines don't spit, sputter, and all the noises that were reported.
Except when they are disintegrating.
The pieces of the engine missing...have you ever been to a crash scene, especially one embedded in what used to be a house? There are always parts that are not recovered. They could have been melted down, trampled over by rescuerers, or perhaps blown clear by secondary explosions after the crash.
From the picture of an intact counterweight in the NTSB docs, it looks like these pieces are fairly large and are made of steel. Hence it is unlikely they would have disintegrated or melted into a blob. If they were not recovered on the scene, it implies they were not at the scene of the crash site. In other words, they could have snapped off while the plane was still in the air. And that fact would have changed the course of the entire investigation.
The props likely shattered when the aircraft hit the ground, while still turning at high speed. Fragments could have been sent blocks away, or buried into the ground, or hidden in the rubble of the house.
Yes, all the prop blades snapped off at impact. And all were recovered.
