US Airways Flight 1549 reconstruction by EXO Esphere 3D
The NTSB released the public docket for Flight 1549 on June 9, 2009. The docket contains a wealth of information that can be utilized in a full 3D reconstruction of the accident. Our work goes deep into the underlying framework of information and encompasses the entire spectrum of accident information. Integrating all spatial and temporal data allows us to approach this accident from a never-before-seen perspective. All work you see on this page would withstand the rigors of qualification for presentation either as demonstrative evidence or, if sufficient witness testimony is available, real evidence. We have the capability to blend all of the information you see into any perceivable final product, depending on your specific visualization needs. The video below is best viewed full screen with HD enabled.
Most people don't realize this, but the birds were visible on radar, before the event occured. 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 illustration 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, time lapse is set at 10x normal speed for this animaiton to aid in visualization. Eagle Flight 4718 actually came quite close to birds but luckily was not on an intersecting flightpath.
