Black Triangle Sighting in Cairo, Cairo Governorate on 2018-08-19 20:15:00 – Very fast object triangolar lights no sound

The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:

I was relaxing around 8pm in my garden with my wife looking for some shooting star, when she pointed at something, asking me if i could see the same strange thing she was watching at.
three steady lights forming a triangle were flying above us (not more than 2000ft)at a very high speed with no sound with a north/south straight direction.
i used to be a pilot with cpl licence, i know planes, and i have never seen anything like that before. i got very excited.
unfortunately i had no time to film it.
