[ARC5] B-17 Crash Near Hartford CT

[scottjohnson1]

FWIW, air tankers such as DC7s and P2Vs have had to deal with reduced manifold pressure limits  when using 100LL for many years. Not a huge issue for experienced pilots and engineers.Sent from my Verizon, Samsung Galaxy smartphone

Reduced MP means less power. Preignition can quickly destroy an engine. Sent from my iPadOn Oct 4, 2019, at 03:40, Doran Platt <jeepp at comcast.net> wrote:
