Engines vs Pastors

Aboard an airplane one day, everything was going fine until an observant passenger noticed smoke coming out of one of the engines. The pilot came on the PA and announced "I'm sorry to inform you that one of our engines has failed, but don't worry we still have three more. This will just mean a slight delay in our scheduled arrival time. Just to re-assure you, I'd also like you to know that nothing will happen to this plane because we are fortunate have four Lutheran Pastors, coming back from a church conference, on board." Someone at the back of the plane piped up "I'd feel far more secure if we had four engines and three Pastors!"
