You read it here first: there will (in all likelihood) be no so-called MoM.
After my last post a few articles underline what I wrote. Richard Aboulafia wrote a commentary in the Aviation Week and Scott Hamilton just posted a story about notes from Buckingham Research, Bernstein Research and Goldman Sachs regarding Boeing and the MoM aircraft.
Goldman Sachs still thinks Boeing could develop MoM, but concludes that Boeing is in a lose-lose Situation here.
Bernstein thinks that MoM could be the "Mirage of the Market" rather than the "Middle of the Market".
Buckingham concluded that the market is not big enough to justify the development.
