Is there any documented case, excluding hijacking, where a passenger or cabin crew member had to fly an airliner (hands on yoke/stick) – even if just briefly – due to an emergency (pilot incapacitation being the most likely one) in which he/she had to replace the pilot mid-flight ?
Aside from talk-down aircraft landings of small aircraft and stand-ins as Pilot Monitoring (which are both beyond the scope of this question), the only case I could find is:
- Helios Airways Flight 522 where a flight attendant was spotted in the captain's seat shortly before the plane crashed
Do you know any other cases ?
I'm particularly interested in cases, in which the stand-in pilot was unqualified to fly this specific plane, but absent such cases all stand-ins as Pilot Flying in an airliner count.
