Engage in a Reconaissance Flight
From Fallen London Wiki (Staging)
Has anybody got more than one landmark doing this? I got one as soon as I got to the second "Far afield" timer from base i.e. over 30. Tried another two "Employ Stealth" but didn't get anything else. I was 100% Employ stealth at 190 shadowy. This % dropped below 100% as I got past 30 "Far afield". This is in the fast & flimsy airship
