as per another thread, you can be a fraudulent war hero or someone like that but that is unlikely to physically hurt anyone, they are not in a position where they have the lives of others in their hands - so to speak.
In the Walts thread I wrote of a former colleague who falsely claimed previous military experience. His claimed experience included using explosives for demolition. He managed to put some large pieces of concrete onto Anzac Parade, a main road in Sydney, miraculously not hitting anyone.
I take your point though, few of these frauds cane take out several hundred people in one stroke as an unqualified pilot can.
