Burlington VT to Denver, CO flight

So I had rebooked my flight from the day before and was at the airport at 5 am to catch my 6 am flight to O’Hara.  Delayed again.  The flight crew had got in at 11 pm the night before and are required so much sleep so we were delayed.  I rebooked my connection to Denver and headed off.  It was interesting, I had never seen a completely snowed and iced over plane deiced.  First they spray a mist of red chemical all over to break free and melt everything then apply a layer of green chemical all over the plane I’m assuming to keep down icing.
