British Airways Incident at Johannesburg
This was not a simple fuel leak. It was 100t of jet A1 escaping through multiple holes punched into the wing tank as a result of the wing slamming into the building. The fact there was no immediate explosion was only a matter of sheer luck. The risk of imminent fire and explosion as a result of the buildings structure (gas/electrical lines) was too significant to not warrant a speedy exit. Accepting casualties here would have been a just call. Witnessing this, If I was a passenger down the back, I would have made my way to the rear exit and evacuated myself! Wrong decision in my book to not evacuate. Very very lucky to have no post prang fire!
