Everyone laughed when MOL suggested single pilot operation. But now we have a situation where there are airlines renting out the right hand seat. If management do not believe you need any more than an old style pilot's assistant (think Bandeirante way back when, maybe Danny remembers) what better way to circumvent the rules and make some additional income. The authorities need to put a stop to this. Sadly it will probably take a big crash to make them take action.
