Narrative:
A C152 on short final to land runway 10. A LR35 no more than 1/4 mi behind him also to land. The LR35 was not sequenced and obviously did not see the C152 because he never said a 'word.' I was just about to relieve the controller in question when I looked out the window and then at the d-brite. I then told the controller in question about this situation. He then issued a go around to the C152 who did not acknowledge. He did it again and this time the C152 did go around on what was essentially a 'runway heading' still only about 100 ft over the runway. The LR35 then passed right underneath the C152 and landed. If I didn't say anything I am positive they would have hit. This controller's lack of awareness is inexcusable. I did inform supervisory personnel.
