Amy commented on Richard's blog post NASA satellite fall on Earth: 1-in-3200 chance to hit someone. How so?
"The size of the satellite must also be taken into account. A satellite as large as Manhattan would have more chances to hit someone than if it was as large as a grain of salt."

NASA satellite fall on Earth: 1-in-3200 chance to hit someone. How so?
How was this statistic computed? Is it based on the formulaQ = 1 - (1 - x/y)^26 = 1/3200,whereIf we pack all 6 billion human beings into a very compact square area, that area will cover x square miles.The total area of the earth is y square miles,Q is the chance that at least one out of 26 pieces (expected to fall on earth) hits the square area in questionIf this is the case, then the human beings occupy a proportion R = 1 - {1 - 1/3200}^(1/26) of the surface of the earth, which is about…See More

Estimating flying parameters when instruments are failing: could it save more lives?
If a plane loses temperature data, could it use interpolation obtained from other planes flying in the same area, same elevation, around the same time? I believe a simple spatial-temporal model could be used to estimate the missing data.Likewise, if elevation or speed is faulty or missing, how about estimating these metrics via spatial-temporal models based on data gathered from other planes flying in the same area?Could such estimates prevent a fatal crash from happening, such as the Air…See More
