In March 2006, Schwartz was among the experts in extraterrestrial events gathered by the United Kingdom's government following the destruction of Big Ben by a crashing alien spaceship. Part of a retinue of UNIT officers drawn from the US Army, he attended a meeting held by acting Prime Minister Joseph Green and General Asquith at 10 Downing Street. He was killed along with the other experts when Green, revealing himself to instead be an alien in disguise, used a remote control to activate devices planted in their ID cards that electrocuted them.

Schwartz was played by an unknown performer.
