Abstract: On July 17, 1996, about 2031 eastern daylight time, Trans World Airlines, Inc. (TWA) flight 800, a Boeing 747-131, N93119, crashed in the Atlantic Ocean near East Moriches, New York. TWA flight 800 was operating under the provisions of 14 Code of Federal Regulations Part 121 as a scheduled international passenger flight from John F. Kennedy International Airport (JFK), New York, New York, to Charles DeGaulle International Airport, Paris, France. The flight departed JFK about 2019, with 2 pilots, 2 flight engineers, 14 flight attendants, and 212 passengers on board. All 230 people on board were killed, and the airplane was destroyed. Visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan.
The National Transportation Safety Board determines that the probable cause of the TWA flight 800 accident was an explosion of the center wing fuel tank (CWT), resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but, of the sources evaluated by the investigation, the most likely was a short circuit outside of the CWT that allowed excessive voltage to enter it through electrical wiring associated with the fuel quantity indication system.
Contributing factors to the accident were the design and certification concept that fuel tank explosions could be prevented solely by precluding all ignition sources and the design and certification of the Boeing 747 with heat sources located beneath the CWT with no means to reduce the heat transferred into the CWT or to render the fuel vapor in the tank nonflammable.
The safety issues in this report focus on fuel tank flammability, fuel tank ignition sources, design and certification standards, and the maintenance and aging of aircraft systems. Safety recommendations concerning these issues are addressed to the Federal Aviation Administration.

Go to www.twa800.com and you will see this "report" torn apart with cold hard facts. Hundreds of 747's were operating that day, with similar fuel air mixtures. After this aircraft's long flight the center fuel tanks were ice cold. If this report is true, then why arent all 747's grounded on account of possible aged wiring which could lead to this same sort of accident. Answer: because it is BS.

In this matter as TWA800 crashed, I expect NTSB should ground all 747s on all carriers to check fuel tanks, If these airlines have problems for the caused of being grounded, that not my fault, but that a better idea.
Air France SST crash nearby CDG Paris Apt, all SST on AF & BA was grounded soon as possible in cities served, some SSTs were grounded @ JFK.
Boeing 767 as Egypt Air, was suspected. All Boeing 767s should been grounded.
Tristar..?? hhhhmmmm I didnt even think if the L1011s had any malfunctions at all.
Boeing 737 rudders problem, Boeing 737s should been grounded as well.
American Airlines ATRs crashed in Indiana, ATR were grounded at all airport served, even Delta ATR's had a problem once on take-off roll while taxiing to runway @ DFW.
If I was able to go and attend the NTSB meeting, I will be the sponsor to ground and inspect all planes orderly and have FAA agree with this situation.
If anyones have questions about how we can discuss this situation, please get in touch, I am aware and concern of these innocent people's LIVES. I am here to HELP.

I'm sure there are some basic flaws in my calculations, but let's assume this:
Since Jan 1985, 657 747's have been delivered. Subtract the 51 freighters, and Exec transports. That leaves 606 747's. Let's say that 95% or 576 are still in service. 576 planes times 2 flights a day with 300 pax per flight = 345,600 pax per day or 126,144,000 per year.
There are over 3,000 737's currently in service. 3,000 times 4 flights per day times 100 pax per flight = 1,200,000 per day or 438,000,000 per year.
Combined pax per year is well over 500,000,000. A butt load of people.
Which do you think would outrage the public more, grounding 3,500 some odd aircraft and all of those people, or another disaster? No one likes a plane to crash, including me...but I think you get the idea.

Which do you think would outrage the public more, grounding 4,000 some odd aircraft or another disaster? I can't say so I'll let you be the judge.
