The North American XB-70 Valkyrie was a great airplane. Only two were ever produced, both of them being test aircraft. One of them crashed in a tragic mid-air collision on June 8, 1966, while the other resides at the Wright-Patterson Air Force Museum in Dayton, Ohio (which I have seen). The picture on the left is a photo taken of the crash site on the day of the accident. The picture on the right is how the crash site looks today.

If you look closely at the Joshua trees along the horizon, you'll see that they are still relatively the same after 33 years! The large Joshua on the left in the original photo is now lying down in the current photo.

Even today, 33 years after the accident, small pieces of the honeycomb wing structure and other debris can be seen lying on the ground. All of these pieces were lying right on the desert floor.
