I wasn’t intimating that a single engine system could possibly be workable, merely using the small plane analogy to illustrate how more engines = more chances for engine failures.

I am 100% hoping for success in this venture.

Probability of engine failure is not important. Probability of arriving safely is what is important.

If a plane can lose any single engine and still land safely, that's a good thing. If it has 4 engines and NEEDS all 4, that's a bad thing.
