"Well little Johnny, when a KC-10 and a 747 love each other very much..."
On a more serious (kinda) note, this is a shot of what happens when ATC fails at spacing its aircraft properly. These two planes flew all the way down the ILS like this which is obviously a bug...but fun to have a chuckle about as well. If you look off into the distance, you can see some other aircraft, also on the ILS lined up against the golden sky...very dramatic!
(Notes: This is v9 scenery, v9 planes, a slow debug build...nothing special here)
