The power of ice! Helped bring down Air France 447 when supercooled water lodged in the pitot tubes of A330 at 35000ft.
Computer was then getting false airspeed readings,switched off and plane goes into unrecovered stall.
I wanted it to stall/slow down a bit-but not stall off Westrn Ireland-SST's 10-11C there!, 8C in Irish Sea

Good........I was hoping for a stall....looks like GFS has underestimated the strength of the block.
To the guy who was wondering why no heavy frost on cars etc-low dew points=very dry air with little moisture to condense.
