saw a sphere zoom past while travelling in an Airplane

I make frequent trips between Salt Lake City and Dallas. Always like to sit in the window seat to see the beautiful mountains of Colorado and Utah.
On May 13th, 2022, returning from Utah, I was enjoying the view outside the window. 45 ish minutes into the flight, a white ball, which may be equivalent to the size of a computer desk, flew past in the opposite direction. Probably at a distance of 100 yards (just a guess). I was so surprised to see something like this that I turned around to talk to the lady next to me to check if she saw the same, but she was reading a book.
I usually see planes at a distance traveling at various distances. While they are fast, they travel slowly in the frame of sight. This sphere/ball was very fast, and I knew it was not normal. A few days/weeks later, US Congress held its UFO report/hearing and was surprised to see a similar sphere in the footage played in Congress.
