Dash 8 with a con trail.
Seen something I have never seen before this afternoon a Dash 8 at about 16-18000ft (estimate) with a very very long and straight con trail heading south between Liverpool and Warrington,
The last time I saw a turbo prop with a con trail was in the 60s it was a BEA Vanguard 24000ft on its way to Belfast going up red 3 over Liverpool, I know it was 24000ft I was listening to it on my VHF Skymaster radio, good days when the a/c used there reg as a callsign.
Nick.
