All midwives that deliver in hospital in the United States are working under an OB. That is what you need to tell your husband. In the unlikely event that a complication does arise that on call ob at the hospital will be right there to do a c section if needed before you are even ready for surgery. True "crash" c section are EXTREMELY rare! When the term emergency c section is used it means that a c section was needed that was not planned before labor started, doesn't mean that baby needs to be out in two minutes that's a crash c section.
I agree with a previous poster that said something about getting your dh on the same page with your wishes is a bigger deal than whether you see an ob or midwife. If you are in labor you are going to have a hard time advocating for yourself and you need someone that is on the same page as you and if you can't get dh there I think it's essential you get a doula.
Also, as mentioned above your provider isn't with you the majority of your labor BUT the nurses will act according to your providers preferences. The nurses know how the providers operate and what each will "allow. So that makes choosing a provider on the same page even more important.
The Improving Birth site might be a good start for you husband. There is a page about "evidence based care" which is a good jumping off point because they cite resources. My husband is an engineer too so I get the wanting facts thing. BTW, I've got him completely on board with the medfree natural route and this is our third baby. Plus his mother and sister are both nurses once you really start looking at the information out there it's hard to deny. https://www.improvingbirth.org/the-evidence-shows/

There is a lot of really great information/advice already given, so I will just add one thought. If you are interested in seeing (or showing your husband) what a midwife assisted delivery looks like, I recommend the BBC documentary series "The Midwives" and "One Born Every Minute." These take place in England, obviously, so the care would look a little different in the US. Personally, I chose to go with a midwife because she, and her assistant, will be with me through the entire labor and delivery. An Ob can not be with you through the entire process (nor should they, as that is what labor nurses are trained for). I acknowledge that this was a priority for me, and may not be for every woman.
The only advice I can give you is to think about what is most important to you. That will help you decide what type of practitioner to go with. That, and make sure your husband is on board. It makes life so much easier!
