What condition were the bodies of challenger and discovery?

The Challenger struck the water at such a high rate of speed that finding all the pieces afterward was a very daunting task. Some pieces even washed ashore eleven years after the disaster. The bodies (or more accurately, some of their remains) were sent to their families for burial, with two being buried at Arlington National Cemetery. The rest of the remains were buried in a communal plot.

The Discovery was not known to have produced any disaster.

The Columbia, however, disintegrated upon re-entry into the Earth's atmosphere. Parts of the shuttle, as well as human remains, were found scattered over parts of North and East Texas, Louisiana, and Arkansas.
