  1. It was called the whale fart theory. The methane bubbles idea had been tossed around as an explanation for why a ship may have sunk under mysterious circumstances. The theory being the bubbles reduce the buoyancy of the vessel. In the case of TWA, the methane was the source of the explosion when the 747 flew through it. I found a reference paper which also adds Egypt Air 990, Swiss Air 111 and AF447 to the list of aircraft that encountered a significant amount of methane while flying. https://www.google.com/url?sa=t&source=web&rct=j&url=https://phe.rockefeller.edu/
  2. You might as well add the huge methane bubble from the ocean floor that it flew into theory....
  3. Having seen the wreckage it is both an emotional experience as it is a fantastic example of a specific type of failure. Hopefully they can capture it in a digital rendering for VR use for future training
  4. This looks similar... http://aerossurance.com/safety-management/ndi-failures-b777-pw4077-fbo/ NTSB report docket: https://data.ntsb.gov/Docket/?NTSBNumber=DCA18IA092
  5. It took a while but I know 5 people in my circle of contacts that have had COVID. Thankfully no serious symptoms; just fatigue and mild cold symptoms.
  6. The Desdemona flight simulator. Hopefully sick bags are included. https://desdemona.eu/
  7. A very interesting article discussing efforts in Europe to enhance hexapod and centrifugal simulators in SUPRA. The information on the improvements made in motion cueing is particularly relevant to this thread. Final report summary on the simulation of upset recovery in aviation (SUPRA) https://cordis.europa.eu/project/id/233543/reporting
  8. A fantastic read. The technical woven around the human experience in the cabin makes the thread so readable.
  9. Agree that motion is a nice to have, not a need to have....BUT.....you need the fidelity of all the other attributes of a level D. The various acedemic studies are hard to argue against.
  10. Mmmm dirt....the filth of freedom.
  11. The glider in the dynamic soaring video above can create acceleration forces as high as 100g at those speeds. Eeesh. https://en.m.wikipedia.org/wiki/Dynamic_soaring
  12. ...because dark colors can reak havoc on composites?
  13. I can still hear his tenor voice proclaiming a 500 foot circuit and established on the downwind left for 28 at Cooking Lake. It was always exciting for us young instructors out of the Muni to hear a legend on the frequency. My first ride on an airliner was on one of Max's 47s in '75 to England. A true pioneer.
  14. Don't forget what the management team did when times were good.. https://www.tsb.gc.ca/ENG/rapports-reports/aviation/2016/a16w0092/a16w0092.html.
