Saw it later on Meridian TV news and surprised it was single crew-looks a relatively large complex aircraft. Not surprised at brake problem theory as it had obviously gone off the end at serious speed.
For once the journos were not exagerating with thier comment that it came to rest less than 6m from a two fuel tankers - if anything it was even closer to two trailer tankers labelled Jet A 1.
Anyway glad the guy got out unhurt-bad luck to have had the accident but real lucky to walk away
