- Vehicle reliabilities not of the same order of magnitude as those of commercial aircraft.
- Impact between deorbiting debris and commercial aircraft. In the case of the Columbia disaster the probability was at least one in a thousand, and the chance of an impact with a general aviation aircraft was at least one in a hundred. The analysis used the current models which assume that any impact anywhere on a commercial transport with debris of mass above 300 grams produces a catastrophic accident:
