Just spoken to a vile Express reader who tells me the basis is as follows:
UK likely to scrap Mk 3s without ever using them and pull any useful kit out for the Mk 2s. However, it could also choose to upgrade them at taxpayers expense...scandal...bah... Boeing says the aircraft were delivered to spec...scandal...bah
The headline tells you all you need know really: 'Copters bungle grounds the SAS'. Without any comment from the mysterious 'SAS sources', of course. Or mentioning that the aircraft actually belong to the RAF, not the SAS. Or that they are really grounded (they could always use other aircraft, I guess).
From a journo - don't believe half of the c4ap you read!
