Flying my personal airplane across the country, 10-8-2020 , thursday was day three and final day of the trip. i took off at 0400 hours. i was over iowa. after approximately 30 minutes into the flight i noticed a stationary light in the sky. to low to be a star, no blinking lights. it remained a constant distance from my aircraft to my front and high. as dawn arrived and the sun broke from the horizon the light seemed to get lower in the sky. i was at 5,500 feet, it may have been at 10,000 feet and to my front by several miles away. as the sun rose the light was gone in an instant.
