Flying Between the Realms. Altered Pilots, #2

Injured and alone, Del's only companion is the strange voice inside his flight helmet-a synthesis of human and alien technology that has merged with his mind to evaluate his worth for the Singularity program. As if the hostile environment wasn't enough, the graveyard is patrolled by blinding, telepathic orbs and haunted by phantoms of the past, including a World War II Mitsubishi Zero flown by an enemy pilot undergoing his own deadly test.
Waiting for him at the end of the line is an impossibly flawless WWI Sopwith Camel.
