A preview for tomorrow's re-entry and Splashdown of Apollo 15. The tragic deaths of the three Russian Soyuz 11 astronauts last month have served as a reminder of how dangerous this part of the mission can be. The Russians have now stated that the cause of the trouble was a fault in the Soyuz itself, in which case, presumably, measures can be taken to see that nothing of the sort happens again.

In the London Space Studio: James Burke with Wg Cdr Tony Nicholson, RAF Consultant in Aviation and Space Physiology and Geoffrey Pardoe, Director of Space Projects, Hawker Siddeley
In Moscow: Patrick Moore

Produced by the BBC Apollo Space Unit
