@Mark. I understand what you are saying and I think the probability should be taken at face value here in the US. When you are flying to a destination across an ocean, then I think you should weight the probabilites against the customer inconvenience AND the loss of revenue while that plane sits at the airport waiting for a part. It's a 2-part problem and not just the cost of paying for the inconvenience of the passengers. Difficult to ship parts that have a higher probability of failing should be pre-positioned overseas to get the plane back in service as quickly as possible. That's how you continue to make money.
Agreed. That's why they call them "scheduled" flights. I think Mark Segal's point is that with proper planning, maintenance, and spare parts (and these all cost $) delays like these can be avoided. It just costs a little more and most flying customers are willing to pay a little more to make sure the flights are safe and on time.
Unless the sun is directly between the earth and Voyager, we get data every time the earth revolves around so the satellite link station can receive the signal. A few million miles across the orbit of the earth around the sun is nothing compared to the distance Voyager is outside our orbit. It's not like when the astronauts were on the far side of the moon.
You have only mentioned the latest adversary, not the ones these systems are designed to protect us against. Don't forget that the Chinese are still Communists and are developing a larger navy and longer range missiles. I personally don't want to see them do what Japan did 65 years ago and they will do it if we don't stay ahead of them in capabilities.
And the list of successful weapons systems is even longer. F-117, B-2, F-15, F-16, F-18, nuclear aircraft carriers, M-1 tank, etc. These were also VERY expensive systems in their day and all very successful in the last two combat situations. Ask the guys who fly and ride in the Osprey if it hasn't improved their combat capability over the helicopters it replaced.
How long were the F-15 and F-16 in service before they were actually used in war-time combat? When your crystal ball that is so accurate tells you what the next air superiority fighter specs should be, then go tell the Pentagon and they can get it right the first time. If you don't have a solution to the problem then quit complaining about it. Developing weapons systems to meet an unknown future threat is very difficult and, yes, sometimes it costs a lot of money. You can come live in Bahrain where I work if you don't like the way your tax dollars are being spent.
Based on the photo under the wing, the concrete break was fresh and most likely occurred when the landing gear rolled over the unsupport slab. The rolling momentum of the plane then collapsed the gear when it dropped into the sinkhole. I agree with Roland that this airport needs to conduct a full structural survey of their ramp pavement to determine if there are other voids under the slabs. You can do it with a heavy chain or steel rod. The sound pitch changes when the chain is dragged across the slab over the void or the steel rod is dropped on the pavement over a void.
