Apinun OZ. Long time, how's tricks up there in the bunker?
The Angolans switched fuels on us a couple of years ago- gave us some really oily stuff with less color and smell than the JetA we normally used- our old Hercs were leaving four big-ass soot trails through the sky. May have been a JP-grade or, more likely, a shipment of kurdish lamp oil they'd got on the cheap. Grounded us for 4 days (...of wine women and song...) while they ran tests. Never did find out who "they" were or what "they" found out, but after 4 days they said "go fly" and we said "where to?" Those Detroit Deisels will burn anything...
Sounds like you guys got same-same lamp oil...
