Thank you Clandestino for taking the time to clarify what you meant. But I cannot see what we are arguing about. AirRabbit has suggested that the AirFlorida aircraft pitched up sharply after takeoff. One thing we can all agree on is that it was snowing heavily as apparently with the Aeroflot aircraft getting back to the original thread. There is no way of knowing how an aircraft covered in contaminant will behave. Ice and snow on the horizontal stabilizer for instance could also significantly change the flying characteristics. It is the luck of the draw if you get away with it. The message is don't do it. Even if you do not crash you can expect to be confronted with the evidence on youtube!
