I know of an Alitalia DC8 over Syria that had a missile go straight through a wing between the two engine installations (without exploding). The aircraft made an emergency landing at Beirut, streaming fuel and hydraulic fluid. Apparently the missile was meant for a Syrian fighter courtesy of Lebanon's southern neighbour.
And of course the two celebrated incidents in the 60s when 707s lost a wing from the outer engine pylon (and engine), one in a midair collision with a Connie, one after an engine explosion. Both aircraft (one PA at SF, one TW at JFK) landed safely, prompting TWA's famous addition to their MEL: "707s may be dispatched with either left or right wing missing."
Never heard of your DC8 incident. Most curious.
