I wont say who but there was an RJ de-iced with cold type one fluid this past winter. It froze on contact with the aircraft skin creating one gigantic popsicle. The de-ice crew found them clean and sent them on their way. If it were not for the high engine vibration caused by the N1 fan blade being frozen in place during engine start and the bearing committing harakiri it could have ended very badly.

Things that make you go ***.
