Alitalia DC-8's have been known to try a landing at Cacina Costa (Agusta Helicopters) instead of Milan Malpensa just across a small ridge to the south. One may have succeeded as I recall.
One is perhaps 4,000 feet long with some factory buildings on one side....the other is a huge airport with an 11,000 foot runway.....and lots and lots of big airliners sat all over the place.
