Problems with black overlap while mosaicking satelite images

Hi, I am attempting to mosaic two Landsat 5 images taken from the USGS GLOVIS site.  The images come as a tilted rectangular image inside a black rectangle, I have attached a screen shot of one image.  When trying to mosaic the images together, the black portion of the rectangle covers a portion of the upper image, as shown in the second screen shot attached.  Is there a way to mosaic the images together without having the black band cover the actual image? 

Some info about the images - the images have the same spatial reference, 7 bands, Pixel type: unsigned integer, Pixel depth: 16 Bit, Pyramids: Level 5, nearest neighbor. 

Any help is greatly appreciated.
