Enjoyment of these radio plays requires one to suspend disbelief and to be willing to escape reality for an hour or so. If you require historical and technical accuracy, then you're going to miss out on some compelling drama. Sometimes, having detailed knowledge of the situation or the profession depicted in the play can cause you to be too critical. I relish the chance to leave my profession and all of the facts and figures behind and just enjoy the play. There is enough stress already. Cheers.
