A note to the wise. Sundance, who will denies Q in is tree house (just go to his blog and post, you will be deleted) spends half his day posting here. Oh yeah, he has many sock puppets and willing shills.
As you were.
That's a flying machine with the greatest lift provided by it's fuselage of all flying machines.
The faster the airflow the lower the pressure. The faster airflow over the top, combined with the slower airflow over the bottom creates higher presser on the bottom and lower on the top which = lift. That diagram doesn't do it.
