DB.....actually 99.9999 percent of my Vietnam flying was with two engines....there were some occasions it was with one....and yes there was one occasion where it was with none.
No snow and ice in Vietnam but well yes....there were lots of hours spent in the "Dead Man's Curve".....and I did think I had died several times but fortunately had not despite some golden opportunities.
For Snow and Ice....I did the Arctic....for the Dead Man's Curve I did lots of forestry and construction work.
So what is your point besides talking like a Prick?
