BOEING 7E7 case study

Part 1: I used CAPM formula to and calculated RE, I also did a calculation on WACC. Please analyze the meaning of these numbers to BOEING company. For example:  The impact of WACC on the expected return to stakeholders and the investor’s opportunity costs. 
Part 1 should take one page or 1,5 pages.

Part 2: What should the Board do? Why might the Board vote YES even if the base case IRR is below the WACC? This part needs to have 1 or 1.5 pages as well.

I uploaded the full case study as well, it is a little long but you only need to get information useful for these 2 questions. Thank you!
