This imagery is available using ArcGIS for Server Image Services on WAGDA. Once you have added the image service to ArcMap, go into the properties to display the footprints. You should be able to select the rasters you need either from a spatial selection or using the attribute table. To download the data, select the tiles you want, right click on the layer and choose Data -> Download Selected Rasters.
