Simplistically it’s true and TBF I was happy to trot that line out for about 20 years, then converted to a relatively modern twin and saw how time had moved on and what that was capable of. Ultimately, yes, a four holer gives you more options than a twin in the case of an engine out ... but as witnessed by the never ending arguments here about the BA LAX flight that continued being able to do so may or may not be a good thing.....
