Question: What was the ball of fire as the planes are landing to the right of the screen?
Answer:That would be a flare being fired from the aircraft. Yellow ones meant the aircraft had sustained serious damage, although that was often self-evident, and a red one meant that there was a seriously injured crewman on board - prompting first aid teams to be ready to meet the aircraft once it had landed. Their was also an unofficial green flare that meant someone had completed their tour of duty.
