Reports Report 638dt (Event 638-2015)

Name Sean B
Experience Level 1/5
Remarks My first thought when I saw the object was, "wow, that plane is really low". Then I realized how fast it came and went and observed to myself, "probably some type of military plane using its afterburners". Total time I witnessed the event could be more accurately described as 3-7 seconds.
