The powerless engine and hole in the fuselage made the plane difficult to maneuver and they lost more than 18,000 feet of altitude in 18 minutes.

That seems mild under the circumstances.
Yeah 1000 feet per minute is not an OMG descent, although PARTS of that descent probably were as they regained control of the aircraft, accounted for asymmetric thrust, and started working the checklist.
Yep, she did a great job that day, but she (or a ghost writer) is also doing a great job trying to sell books with “...and they lost more than 18,000 feet of altitude in 18 minutes.”...which is normal procedure initiated by the pilot with loss of cabin pressurization. Get down to an altitude where the passengers can breath...emergency oxygen masks only last about 10 minutes.
