For a night take off having pad lighting serves little to no purpose. Once you rotate any pad lighting is behind you ie out of sight.
I don't dispute that for one second, that being said it does give you somewhere known to go back to should something go wrong. That being said the AIP references the CAAP. Also who knows what they were doing/planning to do after they were established airborne. I don't pretend that I have read the ops manual that they were operating to, because I haven't.
Really, there's just a lot of un-answered questions that I have.
