A major change affecting the mission occurred when the Agena target vehicle for Gemini 6 suffered a catastrophic failure. This mission was intended to practice orbital rendezvous, a requirement of Project Apollo and therefore an objective of Project Gemini. Borman was at the Kennedy Space Center (KSC) to observe the launch of Gemini 6, and heard two McDonnell officials, spacecraft chief Walter Burke and his deputy, John Yardley, discuss the possibility of using Gemini7 as a rendezvous target. Borman rejected the idea of docking the two spacecraft, but otherwise thought the idea had merit.
