That pic from under the wing is interesting...
I always thought the nose cone hole picked up the air from the main wing plane and passed it through the nose. The picture makes it look like the hole gathers the air from behind the main plane...
I always thought that there would be a good deal of negative or low pressure behind the front wing planes, so how does the cone hole add down force if it picks up the air at that point?
I could just be seeing things incorrectly too, please let me know if I'm out to lunch on this
Thanks
