The preliminary report shows a loss of airspeed in the rotate, and a very early gear retraction. At the same time the aircraft is encountering an increasing crosswind. The pitch angle never becomes particularly high, but the airspeed is low throughout so there was not much energy left to manage altitude with. The gear retraction with a decaying flight path put the plane on the deck and thereafter the engines departed the scene. Overall, a day that the crew would probably rather have a do over of all of their decisions. The longitudinal acceleration increasing just before impact is the vertical component of gravity being measured, although ground speed was increasing relative to airspeed, the plane was in at least a horizontal wind shear, which probably had a vertical component in which could be determined by isolating the component from horizontal only from the underlying energy state of the aircraft for non wind shear conditions. The E JET doesn't have such a pronounced performance loss from the retraction cycle as say a B74 does, but it still unwise to be retracting the gear near the ground under any questionable performance cases, we saw that dump a B773ER on it's butt recently.

This is supposed to be a profession. WTF.
