I think alot of folks might be missing the point sure it will fly around on 3 engines BUT I think if you look to the bigger issue with regards to Regulatory compliance if you have an engine failure Im pretty sure it dont matter if its on a 1,2 3,4, or 8 engine jet. if you are carring pax you are supposed to land at neariest airport. cant find the reg at this moment ill have to look it up I would land!
