Gas and oil recorded without a hitch or a diminution of supply.
But where was his quarry?
Far ahead Bob saw a tiny flare of red in the sky.
He nearly lost control in his excitement, but with the true air-sense he caught the tendency of the sideslip by opposite rudder and aileron and then banked and circled till his nose pointed straight for the dying flare.
Someone in the sky was signaling for something!
“I’ll get there soon! And see!” Bob told himself. He held the ship level, glancing at the “bubble” in the spirit level, as he gave the gun, opening the throttle steadily.
To the roar of the engine, the sing of cool wind in taut wires, the sting of pulsing blood pounding a thrill-song in his temples, Bob took up his quest, and soon saw, ahead, the dim outline of a circling ship. It was dark. Was it brown?
He dared not get too close. Rather, he preferred to climb, so as to be safely out of the other fellow’s way if he maneuvered.
From above Bob planned to light a white flare, by whose light he could identify the ship.
But the other fellow saw him too!
