Air France Flight 447 Black Box To Reveal Aircraft Subjected to Extreme Aerodynamic Forces Consistent With Windshear and Vortex Rich Environment

 Paris -  eMOTION! REPORTS com  meteorological and aircraft structures professionals are advising that the Digital Flight Data Recorder (DFDR)  or "Black Box" data will reveal the Air France 447 Airbus A330-203 was subjected to extreme aerodynamic forces consistent with downburst induced windshear coupled with multiple vortex activity within the powerful storm system the crew unfortunately, if not foolishly, chose to penetrate.
 
"This aircraft flew into an environment completely permeated by wet and dry downburst induced windshear, clear air vortices and opposite flow vortices back-to-back, therein creating the equivalent of aircraft structure blunt force trauma," noted one of our people. "The A330 experienced negative lift at one instant as airflow across either the starboard or port wing, depending on the direction of multiple side bursts of high velocity wind possibly exceeding 200 knots, was interrupted, then followed by updraft (the crew no doubt experienced negative .g; an unsettling experience for pilots not trained to function in such an environment) and downdraft induced uncontrolled climb and descent in the next. No aircraft, not even an A380, could have survived as the aerodynamic loads imposed on the airframe led to catastrophic structural failure. Anyone believing that large, modern aircraft cannot be brought down by severe meteorological events are naive at best, and irresponsible at worst. And, given the enormity and obvious power of this storm system, the captain should have reversed course.
 
"We nevertheless grieve for the victims and their families."

SYNOPSIS


"Northwest Airlines, Inc., Boeing 720B, N724US, operating as Flight 705, crashed in an unpopulated area of the Everglades National Park, 37 miles west-southwest of Miami International Airport at approximately 1350 e.s.t, on February 12, 1963. All 35 passengers and the crew of eight were fatally injured.

"Flight 705 departed Miami at 1335 e.s.t. Circuitous routing was utilized during the climbout in an effort to avoid areas of anticipated turbulence associated with thunderstorm activity. At 1347 e.s.t, in response to a request for their position and altitude, the flight advised, "We're just out of seventeen five (17,500 feet) and stand by on the DME one." This was the last known transmission from the flight. Shortly thereafter the aircraft entered a steep dive, during which the design limits were exceeded and the aircraft disintegrated in flight.


"The Board determines that the probable cause of this accident was the unfavorable interaction of severe vertical air drafts and large longitudinal control displacements resulting in a longitudinal upset from Which a successful recovery was not made."

USAF Tanker Award Update 3/2/11 - Boeing Response to Public Reports Regarding the WTO's Interim Decision in DS 353 - Sep 15, 2010

Publisher's note: In light of the recent award to Boeing for the long awaited US AirForce Tanker contract, prompting pro/con comments from industry executives and policy makers involved in the process, we offer an excerpt from a 9 October, 2009 press release...

Tanker Procurement Process Observations:


"Further commenting on the recent re-release of USAF Tanker competitive requirements after Boeing's successful protest to the GAO against EADS/Airbus, Stokes conveys the viewpoints of several academic, government and industrial associates that the need to preserve C-17 is as critically important as the necessity of having the tanker requirement fulfilled by a true US firm. "'It must be designed, developed, engineered, manufactured and sustained in the United States. This is not jingoism, this is not nationalism, this is not representative of a disturbing naivete as concerns the so-called 'new globality', but rather, a recognition that the country's industrial base must be maintained. Moreover, it must be OWNED and controlled by American firms with a strongly supportive role by the US government as is common practice by other industrialized nations.


"'This is to say, even if the A330-based Tanker were indeed designed, engineered and manufactured here, the question at the end of the day is 'Where does the money go?' Answer: To overseas bank accounts. Also, 'Would there be any guarantees that manufacturing and design would remain on these shores in the event of a global economic schism (again) thereby resulting in calls by company stakeholders to shrink the company's global footprint in the interests of 'fiduciary responsibility?'"


"Based on the recorded activities of international corporations, the answer is no.


"'The idea that obvious illegalities in the form of WTO disallowed EU subsidies designed to give EADS/Airbus ( Northrop-Grumman, with its extraordinary history of aircraft development, is nothing more than, sadly, a front to give the illusion of "Americaness" to their overtures) a competitive advantage in price is dismissed by DoD procurement officers as irrelevant or "having no bearing in the ultimate decision" (paraphrased) is suggesting a departure from logic, reason, conventional wisdom and a complete lack of of understanding that the US defense and industrial bases are one and the same."'


"Stokes suggests a much needed expansion of the DoD's paraphrased assertion that 'we are in pursuit of the best value for the warfighter' would include '...,the American worker and taxpayer.'"


"'To be sure," Stokes further states, ""No other country on earth, neither Germany, France, Italy, Belgium, Spain, Japan, South Korea, China... no one would give away a core element of its critical industrial base which this Tanker, as built by Boeing with its clearly superior aircraft build skillsets, represents.'"
