    Cost of operation

    C-17 …………. $12,000/hr
    C-5 ……………. $21,000/hr

    . . .

    Mission Capable Rate (2008) –

    C-17 ……… 86%
    C-5 ……….. 52%

    Those numbers aren’t applicable to the C-5M

    http://www.airforcetimes.com/news/2009/04/airforce_c5m_dover_042909

    Mission-capable rates for 2008
    * C-5A: 47.4 percent
    * C-5B: 57.8 percent
    * C-17: 86.4 percent
    (The C-5M’s predicted rate is 75 percent.)

    General Norton Schwartz, then chief of US Transportation Command, anticipated a big improvement in the percentage of Galaxies ready for action. “For me, 75 percent is the floor, not the ceiling,” he said.

    . . .

    The Super Galaxy ended the 30-day operation with a 96-percent reliability rate.

    Boeing Exec Predicts First International V-22 Osprey Sale Next Year

    “I firmly believe we will have our first international sale sometime in 2013, or no later than the first quarter of 2014,” . . . there were in-depth discussions with a handful of other countries interested in the aircraft as well.

    “It is more than, ‘Here is a V-22 and what it does.’ It’s, ‘What are the delivery dates? What would be the supportability concepts?”

    A single engine jet’s bird strike = crash = $150 million jet lost.

    don’t forget that a twin engine jet’s bird strike = crash

    (US 1549 wasn’t that long ago . . .)

    Boeing’s T-X Bid A Bellwether For Future Bids

    Davis notes that since Boeing is not bounded by the capabilities of an aircraft that already has been built, the company can tinker with the balance of what learning can be done on the ground and what must be done in high-cost flight hours.

    KC-767 also had a lot of cost & schedule issues.

    well as long as nothing stupid like sequestration happens, all the cost will fall on Boeing (supposedly, we’ll see if they manage to get some back somehow)

    KC-46A is a fixed-cost contract.

    Again, that’s completely irrelevant because that’s not the type of contract the X-32 would have gotten.

    KC-X was envisioned as an off-the-shelf, minimal risk project which is why the pentagon pushed for a fixed-price contract.

    And it should be noted that Boeing STRENUOUSLY objected to that, and that was for a very well understood program. They NEVER would have done it for a completely new, bleeding-edge aircraft like the X-32

    And the Super Hornet was delivered on time and on budget. Boeing has a good track record in terms of project execution.

    SuperHornet was a long time ago. More recent history shows that Boeing sucks as much as anyone. 787 execution was an epic fail and Wedgetail was even worse.

    And the structure of Boeing’s JSF proposal in which the A & C models share a common airframe ensures that an F-35 like disaster would not have taken place with the F-32.

    i have some lovely land in florida to sell you . . .

    And the customers did not pay a dime more; they were compensated for the delayed delivery instead.

    that’s commercial contracts and NOT what would have happened if the X-32 had been selected

    X-32 would have gotten standard cost-plus contract just like the F-35 and would have been massively overbudget and behind schedule just like the F-35

    The original JSF plan was to have two airframes, and both airframes would have 80% parts commonality, and this would have been achieved with the Boeing plan.

    And what makes you think the Boeing plan would have worked any better than the LockMart plan when the X-32 had less lift margin to begin with?

    1. Boeing does project management much better than Lockheed due to its commercial aviation roots.

    *cough*787*cough*

    The F-35 program has A&B models as common airframe, so the A model’s screwed if the B model’s screwed, and that’s exactly what happened. A very poor project planning on Lockheed’s part.

    no, all 3 airframes are unique

    anyways, back on topic,

    http://www.flightglobal.com/blogs/the-dewline/2012/10/usaf-releases-draft-t-x-kpps.html

    One of the requirements is that it should be able to take the place of the F-22 bridge course (Eight rides in a two-seat F-16, doing night aerial refueling and making sure the new guys can pull 9Gs while operating the radar and what not) before new pilots head to the Raptor B-course.

    is that actually in the docs, or is he just talking about what is currently done with the F-16s?

    Exclusive: Brazil delays jets decision until 2013; Boeing ascendant

    Brazilian President Dilma Rousseff has decided to wait until mid-2013 to make a decision on a multibillion-dollar Air Force jets contract, and Boeing’s chances of winning the deal have improved due to its recent alliances with local aircraft maker Embraer, two senior officials told Reuters

    . . .

    Rousseff herself will make the final decision on the jets, which will help mold Brazil’s military and strategic alliances in coming decades as it seeks to establish itself as a major global power.

    The contract is on hold in part for budget reasons, one of the officials said. Rousseff just emerged from a tough battle with public workers over wage increases, and it would be politically difficult for her to approve billions of dollars in spending for military hardware so soon after alleging that finances are tight.

    . . .

    Reuters reported in February that Rousseff was leaning toward Dassault’s Rafale. However, since then new concerns have emerged about the Rafale’s high cost and especially the terms of the technology-sharing that Rousseff believes are the most important factors in the deal, the officials said.

    Meanwhile, Boeing has earned points by announcing a series of partnerships with Embraer, which is aggressively expanding its defense operations. Embraer said in July that Boeing will supply weapons systems for its Super Tucano fighter, and the U.S. company is also helping develop Embraer’s KC-390 military transport and refueling jet.

    Reuters also reported in February that Boeing has frozen the price on its bid since 2009, an unusual step that is believed to have amplified the F-18’s cost advantage over the Rafale. The per-unit cost of the jets has not been made public.

    “Boeing is definitely looking better in the last few months,” a second official said.

    The problem with AF447 was it’s pilots.

    Which is why pilots shouldn’t be allowed to crash planes.

    The sad thing is that there is already something in place to avoid this issue. It’s called flying the plane.

    The same thing can be said about almost all accidents.

    “There’s a proceedure for not flying into mountains. It’s called avoiding them.”

    The point is that humans are human.

    No – don’t like that.

    There are niche cases when you have to crash into the ground/ditch on water (landing gear failure or birdstrike for instance).

    In those instances, I’d probably prefer the pilot to have final control with advice coming from the computer.

    obviously it would be possible to override by putting in landing mode or with the big red override button or whatever, but unless the pilots take specific steps to disable it, it will keep them from crashing
