Courts etc
This case is highly unlikely to go anywhere near a Civil Court (the High Court in this Country). This is because the owner of an aircraft is strictly liable for injuries caused on the ground by their aircraft. For those really interested, look at Section 76 (2) of the Civil Aviation Act 1982. Strictly liable means no proof of negligence needed.
An admission of civil liability has already been obtained by some of the families from the owner, and its insurers.
The interesting just culture question will be where the Criminal Investigation leads.
