Extraordinary graphical recreation of the accident sequence. Interesting crew dialogue descending through 300 feet.

Excellent find sir!

I was interested to hear that the birds were visible on radar.

After integrating the raw radar data into our 3D environment and creating motion targets representing those radar returns associated with the flock of birds, our timeline clearly depicts the intersection of Flight 1549 with birds at a time of around 1527:10 (HHMM:SS). This coincides well with the CVR transcript which indicates loud "thumps" at 1527:11.4 (HHMM:SS.0). The NTSB Wildlife Factors Report has identified the feathers in the aircraft as Branta Canadensis (Canada Goose) by means of visual, microscopic and DNA analysis. Identification of the feathers was conducted by the Smithsonian Institute Feather Identification Laboratory. Though the errors may be intolerable, it is possible to pursue an altitude calculation for the birds by triangulation, this due to the fact that there are two separate radar facilities that reported data. We know the altitude of the birds at the time of impact, but it may also be helpful to determine their flight profile to understand where they were going or where they departed.. We will attempt this analysis as our work continues on the accident.

The timelapse (10x) animation below presents a detailed view in the area of the bird strike and clearly shows motion, disorganization of the flock following the bird strike, and the subsequent re-organization of the flock(s) following the passage of a second aircraft, Eagle Flight 4718. Aircraft altitude is in 100's of feet. Eagle Flight 4718 actually came quite close to birds but luckily was not on an intersecting flightpath
Other than gassing thousands of birds and killing some eggs (after the fact) it seems that this could have been prevented, no?
