My first ever flight was in a Viking - Channel Airways Southend to Basle. I was 11 years old and the crew allowed us to go up on the flight deck. To my knowledge she didn't tip forward. I do remember having to climb across the main spa to get to the front of the aircraft. It was like a small set of steps. Also I remember there was a fairly healthy ribbon of oil from the starboard engine throughout the flight. Long time ago but happy memories.
