Didn't the F4 have a Dog Tooth on the leading edge and the Bucaneer had a blown wing. Tiny holes on the up surface of the wing expelling bleed air from one of the engines. Which meant if one of the engines failed you not only lost thrust but a portion of lift as well. From what I was told though it made it a very nice acft to fly.. .. .The Metro three has a fence just inboard from the landing light nothing aerodynamic just prevented the pilots from looking directly at the landing light.
