Yes indeed, and that is exactly how the UK would have to man it once the last WSOs have moved on.... we have now closed our WSO training system! Nowt wrong with putting 2 pilots in together; in fact you could argue it would make for better co-operation as each would instinctively know what the other was supposed to be doing and when, helping each to know when to talk and when to shut up.... this can be a problem with some of the chopped-early-in-flying-training WSO brethren...
