B747 & B707 Pointy things.
Hi got a question about some of the older model B747 aircraft pre 400 model ie before winglets. On these older model 747s at the wing tips on the trailing edge there are long pointy things sticking out what are they?
Also on the B707 at the top of the tail there is also a long pointy thing it facing forwards looks somewhat like a pitot tude what are these ?
Sorry for my technical jargon about the pointy things just curiosity really.
