Original Note:
Flights in the same direction are multiples of 1000 ft apart in altitude. That difference in altitude makes one plane look faster. Atmospheric conditions vary at different flight levels. Those conditions determine the formation of ice crystals, also known as contrails. https://www.faa.gov/regulations_policies/policy_guidance/envir_policy/media/contrails.pdf
