I was looking at Moffitt Field in San Fransisco and noticed a plane in the corner of the field. I'm pretty sure its a wind tunnel model cause of the location but For the life of me I cant identify what its for; as a delta wing its too stubby for a quiet SST design, and very inefficient as a sub sonic passenger aircraft. It sorta looks like a F4D but the air intake is wrong and none are know to be on display in the area. Because it has a cockpit this unknown aircraft is not a UAV design. Any ideas?
