About 22 years ago, my 2 school friends and I, at around 14 years old used to wonder why we saw 3 planes going across the sky above our school field back and forth all day everyday. For months it caused me anxiety (thinking it was Iraq planes not understanding radar and defence!) but I now know it was more than 3 planes and so often due to flight path!
(I accept not v AIBU) I remembe how, watching these planes one clear day, one appeared to briefly drop and spin around front-to-back-front again (though very high up)and continue flying. At the time I saw this, my other friend also giddly/faux-horror screamed as she saw it too.
The planes must have just been regular passenger jets. Is what we saw possible, and if it isn't, what could have created the illusion we both saw?
