Thanks to this video shared by @air_english, here is an example of the kind of accident you can avoid if you follow some basic flight safety rules. Even if nobody could expect such a spectacular accident while weather and visibility were excellent, some precautionary measures could have prevented the aircrew from a catastrophic failure. This video will let you guess what provoked this. You will find an analysis of this German Robin DR-400 accident here.

Thanks to AIR-ENGLISH and John Maxwell. Please, pass the information on for it is a flight safety issue and it could happen to anybody. It is useful for BIA-CAEA too.


New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):



  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

Rio-Paris AF 447 crash – Incomplete investigation report

Regarding the 2009 Air France Rio-Paris crash, and according to the BEA investigation, it seemed to show a lack of training. But it now seems to be more complicated- it turns up that the elements of the report on the investigation were actually incomplete. This scoop – according to this France24 video – comes from the French paper La Tribune. Several elements would have been taken out of this report, and more importantly an element about a malfunctioning stall alarm:

Air Traffic Control – Interesting voice communications with scripts

Caution: As far as this video is concerned, it would be well advised not to use some of the phrases heard on its soundtrack during an FCL 1.200/1.028 speaking examination…
