Did the 105 or F4 have BLC and if so what indications did they give the

It would be good to hear from Walt or maybe even Ed Rasimus may know?
Thanks for your input Dudley....and thanks to you and John Ward in regards
to the 51....I can't wait.

The F-105 did not have BLC. The F-4 did, prior to the soft wing, for
both leading and trailing edge flaps. I don't recall any landing check
of engine indication for BLC proper operation. The BLC was checked by
the crewchief during preflight when flaps were lowered by his simply
running a hand along the area to feel the blowing. There was a warning
circuit for BLC duct pressure that illuminated a caution light on the
telelight panel in the event of a line rupture. That was very serious
emergency as the superheated air would quickly lead to structural
damage to the wing.

In later years some portion of the BLC was eliminated, but I don't
recall which parts. Maybe someone with some soft-wing experience can
recall.
