How does this happen?

Posted: 15 Jan 2006, 12:18Well that's what I thought, but currently there is only one flight a day from Boston and that departs in the evening. Can anyone remember if there was an early morning flight from BOS last feb?

If you look at the service vehicle in the lower left of the pix, it is also covered with snow. I think Sailor has nailed it.

It certainly wouldn't happen in flight. The flightdeck windows are electrically heated to eliminate condensation and ice buildup.
Also, at 35000 feet, the air outside is so dry that any ice buildup would usually be on the inside - which you may have noticed form on the pax windows in flight.
Ice buildup on the outside of an aircraft in flight usually happens at lower altitudes if the air is humid enough, and when flying in cloud.

Posted: 15 Jan 2006, 16:40Cant comment on this particular flight but if it was at Boston then must have ahd an extended ground time for one reason or other.Even on the ground the windscreens are normally heated. Obviously all this snow and ice would be removed before flight, usually by use of a hot de-ice fluid. Sometimes seen being done just before a flight mainly on the wings though.
