    Russia is not near to being the the second most dangerous place to fly in the world, the Russian aviation authorities have certainly improved their act in the last few years. I would fly in Russia, and have done so in the past.

    Second most dangerous country to fly in? Try Indonesia…

    Question if they take hull loss rate (which takes hull losses per take-off, but doesn’t factor in the passengers on board), or the number of death bodies per travelled distance. While the layman would consider the latter more meaningful, for flight safety the first is of higher importance, as the flight safety is best expressed as how many aircraft (irregardless of their size) are lost per 1 million take-off & land cycles (again considering the low impact flight time has on accident probability).

    The comparison of Russia versus Africa is a bit odd as IMC is more likely in Russia.

    As usual too much blame is put on the specific aircraft type.
    Fact is that even a Tu-154 can be operated perfectly safe, the operators are to blame.

    Africa and Russia have one thing in common: lack of safety culture.

    By the way: traveling in Africa is dangerous no matter which mode you chose. Such articles often imply that it is extremely dangerous to use an aircraft in Africa, while making a trip with the railway or by car is even more dangerous. Africa is – for Western standards – generally a dangerous place.

    Strange action to blame your project partner.

    Disagreement with previous post!

    The A400M is a very good aircraft, but will have an aweful lot of technical issues in the beginning. However, that is true for nearly all military (and recently all civil) projects.
    Antonov crashed two prototypes and still doesn’t have a production-ready aircraft, after over ten years of development.

    Personally, i think it look incredibly front-heavy! god only knows how it’s gonna keep the nose up.

    Chinese pilots are not that heavy. :diablo:

    What are the chances of us seeing a Berkut,Mig1.44 style tech demonstrator from the Chinese (just for the hype) soon ?

    According to Chinese media, including official CCTV, the next generation fighter after J-10 will take maiden flight very soon.
    Variant voice from different side of designers said that we are confident our new generation fighter will go ahead of the F-22 and it needs 10 years to surpass the F-22 to both.
    A via commander also said 8-10 years should be waiting for entrance service of the new fighter.

    B.S.-Flag is waving in the wind.
    The present J-10 ain’t better than the F-16C (which isn’t bad), and China is gaining land. But it takes time.

    Failed by a big margin to boot;- it only made 70 % ultimate (i.e. 105% limit)

    I think that margin of failure is without precedent in the last 40-50 years

    The Lockheed Galaxy failed at 120% LL. The B787 wing did not fail, but there was delamination of some structural parts. I wouldn’t call that a real failure, but it was close to it.
    The fact that a structural part fails does not mean the whole aircraft is a mess or unsafe, it rather points out that the processes and tools used to design the aircraft are not well established. Many structural parts needs redesign, in any aircraft program, but the general public normally doesn’t learn about it.

    Might I ask a dumb question ?

    Why is it so difficult to produce a cargo version of an already established passenger airliner ? Don’t they just leave the seats out and cut a wider hole where the passengers normally get on ???

    The fuselage needs strengthening, and that is not that easy. You can see the difference when you compare the payload of new delivered freighters versus converted aircraft.
    Also a number of system need to be changed.

    Correct is that it is not really a “first flight” as most critical system and the primary structure for flight remains unchanged.

    Half a chance the A-400M will end up replacing C130J’s in a few countries once they get the bugs worked out. Because even the C130J doesnt have the capacity to carry a lot of the newer armoured vehicles, while the A400M, even though overweight, does have that capacity.

    And what limits the MTOW of the aircraft?
    Maybe the better step is to soften the requirements, the A400M is sized in many respects by soft field landings and other military stuff. When it flies from 8000ft runway to another 8000ft runway such limitations are not in place.

    Safety systems are intended for such events. The crew performance must be investigated. But permanently suspending the crew from duty is the wrong step. Taking them out of the schedule while investigation is running is reasonable.

    Does anyone have an idea as to what Dreamlifter development cost was?

    I would put in the mid 3digit million region. Design was largely done by engineers in Russia. There are only two aircraft and I doubt they have full certification.

    Fact is that RyanAir earned money with selling its B737 to other airliners. In the peak times in 2007 you could sell used aircraft at close to list prices. When you only pay ~50-65% of the list price and sell it for 80%, you make a profit.

    wonder if engineers of today are less competent? in the 60:s they landed on the moon with help of an small calculator?!

    The A400M specs were not made by the engineers.
    The A400M time schedule is surely not from engineering.

    Engineering has less control over programs than it had in earlier years. Aviation is becoming more and more business-oriented, but for high-tech that apparently is a flawed approach.
