Sports team charters seem to figure quite bit in these kind or RTO or landing over runs, I suppose the guarantee the incident makes the enws but I wonder if the fact that most of the pax are approaching twice the weight of the 'standard' pax might mean the actual weight is rather more than the books suggest
On team flights they use team provided weights for pax and luggage, not standard weights.
They keep having incidents because most of them are sh!tbag operators putting excessive pressure on their crews.
