“Yes, phone him. I’ll report soon. Please start serving dinners, Jean. We must keep it pleasant aboard just as usual.”

Vicki hastened back to the Bryants. She covered the man with the blanket.

“Miss Barr, I must tell you”—Mrs. Bryant made an effort to control her trembling voice and hands—“that my husband is more exhausted than ill. He had three quite tiring days in Chicago on business, and it’s been hard on him.”

Vicki said soothingly, “Certain people need extra oxygen at high altitudes, where the air is thin. Our cabin air is pressurized, but for someone who is a cardiac, and for other special needs, we carry extra oxygen.”

As she talked, she placed the oxygen bottle on Mr. Bryant’s lap; he was able to hold it steady. Vicki opened the bottle’s knob, then adjusted the constant-flow mask snugly over Mr. Bryant’s mouth and nose.

Almost at once his breathing grew easier. A little color returned to his face. When he seemed comfortable again, Vicki removed the mask and closed the knob. Just the same, she was worried. He was still weak, and he was an elderly person with an impaired heart.

“Mr. Bryant, Mrs. Bryant, if you wish to have a doctor’s care within just a few minutes,” Vicki said earnestly, “we can arrange it for you. The pilot can make an emergency landing. Captain Jordan will radio ahead to the nearest airport to have a doctor and ambulance waiting to meet our plane.”

Mrs. Bryant murmured, “That’s wonderful. What do you think, Marshall?”

“No. Not necessary. Make myself conspicuous. Inconvenience all these people.”

“Not at all, sir,” Vicki said. “Captain Jordan probably will be able to make up the time.”
