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 reported glowing green triangle ufo yesterday that i photographed on flight from dallas fort worth airport. i now think the glowing green triangle was a reflection from the fasten seat belt sign. i dont know this for sure. but i looked online for an image of fasten seat belt sign and there is a green triangle. i feel really silly and embarrassed. sorry. i know tyler from secure team posted it today. i am a fan of his channel and was very excited to see the post. when i read through the comments, someone said it looked like the play button. i know it could not have been that because there was no tv on the spirit flight and we had not pulled out our electronics yet. then i thought about what the fasten seat belt sign might look like. i looked it up and grabbed an image and sure enough it was a green triangle.
