...and you can go below DA, providing you don't bust the OCA.
Some might be interested to know that with older straight-pipe 707's at max landing weight, the go-around maneuver from decision altitude (200 feet, for example) often resulted in the main landing gear just touching the runway, due to the slow engine spool-up times.
Legal?
Yup, then and now, even with newer aircraft....although with newer types, engine spool-up times are much shorter, so this is of little concern.
Just be sure you don't try the 'duck-under' maneuver, least your main landing gear get tangled in the frangible approach light bits.
