The 21 April 2002 X-class solar flare exhibited supra-arcade downflows of the type described by McKenzie and Hudson (1999). The flare was observed simultaneously by several observatories, and the downflows were clearly imaged by TRACE and SOHO/SUMER. We present a comparison of the TRACE and SUMER data concerning the supra-arcade downflows, and demonstrate that the dark downflow features are consistent with regions of locally depressed plasma density. Furthermore, the implications of the oscillatory behavior of the supra-arcade spikes for coronal seismology will be considered.
