Of course it was. Like millions of flights before it.
That's about the failure rate of anything mechanical on a plane - MILLIONS of flights.
How many flights did it take for a piece of FOD to be picked up by a tire and hurdled into a an engine of a Concord causing a catastrophic explosion - hundreds of thousands (or more) for just one aircraft type? Or, maybe that was a missile too.
Catastrophic mechanical failures are rare. However, that doesn't mean that they don't happen.
