I discussed this years ago at the duty desk. The theory was that in a Hornet, with weather below TACAN mins, all you’ve got is the PAR to get you down. If you’re NORDO, that means you’re sucking LAU down to the runway—formation landing. There simply isn’t enough time to execute flight lead sep on final if you’re breaking out at 200’ AGL. Made sense to me.
Only did it a few times. Once was a syllabus item, others were prebriefed ‘why not’ form landings.
It was fun, and a good tool for the toolbox, imo.
