Daughter just got in....her view was around 10 seconds total....
She said the plane was totally vertical from the time she saw it till impact. No real engine noise just a loud whistle, no smoke....plane was completely intact until impact, nothing noted unusual in control surfaces....did not twist or spin....straight lawn dart....directly into the house....houses on either side were untouched....
BTTT ...
They say there was only a single pilot on board. Family from destroyed house was at church. 1 fatality, no injured. Really lucky considering.
I am going through a Citation recurrent this week. Evidently the pilot was a seventy year old, single pilot qualified, reported auto pilot difficulties. It would have to be some kind of hardcover and failure to disconnect. There are a couple disconnect features on the autopilot, but there has been another autopilot disconnect mishaps many years ago.
