Lockheed made the C5, and I've always held they made the best jet airliners. The jury is still out on what exactly happened. It may have been a clean single-engine failure and a screwup in the ensuing emergency. The way they hit -- wings level, hard, short, and lined up -- doesn't give any obvious help either way. They could have lost another engine, or had their LEDs and flaps all fowl-ed up; Or they could have screwed up the approach configuration, or miscalculated the numbers for an overweight 3-engine landing, and gotten into an unrecoverable position (AoA too high and speed to slow). We'll probably find out. Don't go blaming the crew right before at least some facts are in.
One thing we can say for certain, the crew could have done worse.
