So basically, VT-ANB ( Victor Tango Alpha November Charlie) was not a terrible teen 787 but had the same production challenges. It was in storage until 2014 because it had extensive re work done and some of it included wiring and Boeing did all the repairs. Later in January 2022, while it was flying Delhi to Frankfurt, it had a P100 fire and again Boeing did the repairs. I think that there might be faulty wiring that sent ghost signals which might have turned the fuel switch off . This is only speculation and certainly doesn't explain what happened to VT-ANX ( Victor Tango Alpha November X-ray) and I am certainly not an aviation expert but rather an amateur Avgeek.
