The 150 pax on the first sector DUS-BCN were extremely lucky indeed: probably Captain did not leave cockpit to go to the loo and this saved their life.
It would also be interesting to see what pills the FO swallowed very early in the morning before starting his duty: all anti-depressants and anti anxiety medications have very strong side-effects including suicidal thoughts, amongst many other pretty scary and dangerous symptoms.
It would be even more interesting to find out how many pilots do regularly use anti depressants before flying, possibly too many, ...is this the direct result of a very stressful life where we are all mistreated as profit making numbers by Lean Six Sigma & Pareto Charts' inspired management?
