Hi,

Mr. Jay Miller spoke about the Douglas Type-499 which later led to Type-499D
(the X-3),as it had a twin Westinghouse 24C turbojet/rocket boosted aircraft with
low aspect ratio wings and a jettisonable nose section for pilot recovery in case
of emegncy.

A similiar escape system was contemplated for the Douglas proposals 684 (also dubbed as D 558 Phase III).

I know three distinct designs submitted to MX-656 by Douglas, and they're attached below. I would imagine they all fell under the DS-499 program, though I couldn't say for sure.
Second of these proposals (no particular order) is also shown in model form. Third proposal was closest to the built X-3.
