Landing at night on the east coast of the Domican Republic in a 727 came out of an NDB approach and trying to make the VASI show proper glideslope realized that we were way too shallow so leveled off and did an all white approach. Maybe a mule stepped on the approach end of the VASI but it was at about 1 degree. I warned our NY arrival flight not to use the VASI when we departed. If it doesn't look right it probably isn't. It was Punta Cana. I was a new captain and we were sent copies of approach charts so I was being extra careful. Those are the nights you can get in the headlines if you are not careful.
