and despite the fact that the turbine blades are subjected to enormous
centrifugal forces.

When this goes wrong it goes badly wrong.
In 2010, an oil tube went leaking aboard a Qantas A380 (
QF32)just left off Singapore on the way to Sydney.
This resulted in a breakage of a turbo fan which shrapnel flew through the wing and cut all wiring for the communication between avionics and engine. The Qantas control center in Sydney got a long stream of unexplainable error messages.
The captain finally succeeded to turn back to Singapore and land it safely, but it almost crash-landed with over 400 victims.
