The approach flown was a CAT I ILS. I could see the rain column approach from the other side of the field so I got out my phone camera from the jump seat. You can hear the GPWS announce minimums at 200' AGL, and shortly after all visibility is lost due to rain. You do not hear the "50" foot call out during the touch and go, but it had to be close. The HUD really provides incredible center-line tracking, although you can't see the symbology from the camera angle.
