if full house then: 140seats + crew + infants(sitting on lap) =SOB
Yes, I realise that, but it's not unknown for seating capacity to be exceeded in that part of the world. 140 seats, cockpit crew 2, cabin crew 3, plus 8 infants = 153 ..... it's possible.
More surprising is that whilst some sources are quoting it crashed on finals inbound from Abuja, others are saying it crashed on take-off from Lagos. Even AV Herald comments differ on that.
