I've been hit in the engine twice in a P47-D-25, and both times it caused a fire (well, lots of black smoke with no visible flames), and I exploded. I caused a fire on one nme plane (p51D), but I could see flames around his wing root. I watched him heading off before disappearing suddenly followed by a kill report. SO: 1) jugs catch fire too easily right now and are flying molotov cocktails. No doubt this will be speedily addressed. 2) flames from fire are down around the wing root where they are hard or impossible to see from inside the cockpit. With the absence of that real life toasting-toes feeling we have to guess from the type and amount of smoke that it's time to get out of the plane right quick and walk home.
