I have an idea that Boeing puts out requests to component manufactures for items that meet specific design requirements for specific model airplanes and that these components are not interchangeable with other models and are not used by other manufacturers. Having said that, maybe all components that fit the B747-200 are also used on the B747-400 and therefore would be available for a long time. So maybe my post is entirely out of place and I apologize.

Don't need any new Air Force One airplanes? Just when does Mr. Trump think they should be replaced - when they are 40, 50, or maybe 60 years old or older? Air Force One should probably have 4 engines, so where would he find any that many years from now? They had better get them now while they are still available. The cost to keep the old airplanes flying is not very inexpensive either, so new ones just may be cost effective. There must be parts for the B747-200 that could fail or wear out which would no longer be available anywhere and the spares are all used up, maybe something as basic as a hydraulic or electrical component unique to the model.

In reality, I think, taking consideration the time zone change, the flight is 1 hour 20 mins. one way and 1 hour 10 minutes for the return flight. The departure and arrival times are from gate to gate, so it would not be possible to travel 235 miles take-off to landing instantaneously with a 10 minute taxi at each end.

The analysts conclusion that the cross section should be elliptical in shape may be a very expensive proposition. Here we go again, trying something new (read composite construction on B787) that has not been done before and would undoubtedly extend the development time and certification time and be radical enough and so expensive that it could sink a company even as big as Boeing. That would be a BIG new airplane project, for sure.

Maybe there should be X marks on the end of the taxiways to indicate that they are not to be used as runways. This is definitely an accident looking for a place to happen.

The video that I watched took the time to show the placing of every one of the individual payload satellites into orbit. Nothing missing!
