During the horizontal part of its trajectory, the object moved across the
sky at a rate of lo degrees in 9 seconds. With an estimated altitude of
40,000 represents 15 miles per minute or 9o0 miles per hour.
After about lo seconds of horizontal go into
a vertical dive. The possibility that the appearance of a dive was produced
by ths object merely receding into the distance seems unlikely since the
speed normal to the line of sight was undiminished in the dive. The dive
lasted for from lo to seconds at the end of which tims the object was

the sun for perhaps a second at a time. Just at this time the vapor trail

unrecognizable, was seen through the theodolite, not as a glare of (reflected?)
light, but as a grey mass in the act of levelling off. Its size in the
theodolite field was of the same magnituds as the 79 ft. balloon, which means theodolite field was of the same magnituds as the 79 ft. alloon, which means
