"What is it?" Steve asked.
"I know!" Rick exclaimed. "There were a few times when people said they saw yellow glows in the sky after they saw the objects. Isn't that it?"
Scotty nodded. "I've been counting. There were five instances. Two people said the glow wasn't really connected, because it came from Wallops Island."
"Why on earth didn't you include it in the chart?" Steve demanded.
"It doesn't fit," Scotty replied. "In every single case, the glow was to the southeast."
"Maybe it does fit," Steve said emphatically. "Boys, never leave out a bit of data because it doesn't seem to fit. This particular chunk could very well be the clue."
"Why?" Rick asked quickly.
Steve shook his head. "I'm not sure, so I don't want to say. But include every sighting of the yellow glow on the date cards. I'm going to borrow that set for a closer look."
Scotty began reading, while Rick recorded. When the cards were complete, they ran through them. There was no periodicity. The dates seemed completely random. Sometimes two sightings had been made at different times on the same date. There would be two days, three, four, five, or even six between sightings.
"Not a trace of pattern," Rick said.
