I don't suppose we will ever know why the Jag went into that field, and we may never know why the Firefly ended up as it did at the weekend.
Sometimes we just never find out. I think it is healthy to look at possible causes, but very unfair to suggest that Pilot Error is likely, simply because there is no evidence of mechanical failure or other interference.
You have succinctly put your finger on the difference between these two tragic accidents, one military and investigated by the operator/regulator/investigator, the other civilian where operator, regulator, and investigator are all separate from, and independent of each other. The first arrangement is now surrounded by scandal and cover up, but the second will ensure a professional and thorough investigation that we may have confidence in to ensure the primary aim, which is always to prevent a recurrence. That at least should bring some comfort to the bereaved loved ones to whom we can but offer our deepest sympathy.
