I see that we have two types of critical systems :
* Systems that are designed with a human as the ultimate layer of protection: cars, planes
* Systems that are designed to be the ultimate layer of protection
If there is a material possibility to inhibit or disengage the last ones, there is almost nothing guarantying that this will never happen, intentionally or not...

Subject: [SystemSafety] Alton Towers was HF
For those who don't know, an amusement park in England, Alton Towers, suffered an accident on its new Smiler ride on 2 June 2015 https://en.wikipedia.org/wiki/The_Smiler_(roller_coaster) Some people were seriously injured.
The UK HSE has prosecuted the owner and court proceedings have just started. The owner has pleaded guilty. The technical engineering was all OK. The human engineering not so. Summary: it was HF.

A question for those of you in IEC SC65A WG 17 on HF and functional safety: does your current proposal require measures which, had they been followed, would have avoided this accident?
