The SkySat is not intended to fly at 30,000 feet, but at 8,000 to 10,000 feet. It is interesting to note that there are currently scheduled test flights, but we don't know which airships are involved.
Now, today we see reference to S2 being readied for flight testing at 15,000 to 30,000 feet, which Egbeck (correct me if I'm wrong on the poster's I.D.) pointed out is a higher initial test altitude than previously mentioned in regard to the S2.
Thus, what if a smaller airship, say the SkySat, will be tested at the lower altitude prior to the S2? Those tests and the data obtained would perhaps permit higher initial altitude testing for the S2 at 15,000 to 30,000 feet as opposed to the original 5,000 feet previously mentioned.
