A simulated dogfight training took place between two Israeli F-15D's and four A-4N Skyhawks over the skies of the Negev, Israel. The F-15D #957, (nicknamed 'Markia Shchakim', 5 killmarks) was used for the conversion of a new pilot in the squadron. Here is the description of the event as described in "Pressure suit":
"At some point I collided with one of the Skyhawks, at first I (Zivi Nedivi) didn't realize it. I felt a big strike, and I thought we passed through the jet stream of one of the other aircraft. Before I could react, I saw the big fire ball created by the explosion of the Skyhawk.
The radio started to deliver calls saying that the Skyhawk pilot has ejected, and I understood that the fireball was the Skyhawk, that exploded, and the pilot was ejected automatically.
There was a tremendous fuel stream going out of my wing, and I understood it was badly damaged. The aircraft flew without control in a strange spiral. I reconnected the electric control to the control surfaces, and slowly gained control of the aircraft until I was straight and level again. It was clear to me that I had to eject. When I gained control I said : "Hey, wait, don't eject yet!" No warning light was on and the navigation computer worked as usual; (I just needed a warning light in my panel to indicate that I missed a wing...)." My instructor pilot ordered me to eject.
The wing is a fuel tank, and the fuel indicator showed 0.000 so I assumed that the jet stream sucked all the fuel out of the other tanks. However, I remembered that the valves operate only in one direction, so that I might have enough fuel to get to the nearest airfield and land. I worked like a machine, wasn't scared and didn't worry. All I knew was as long as the sucker flies, I'm gonna stay inside. I started to decrease the airspeed, but at that point one wing was not enough. So I went into a spin down and to the right. A second before I decided to eject, I pushed the throttle and lit the afterburner. I gained speed and thus got control of the aircraft again.
Next thing I did was lower the arresting hook. A few seconds later I touched the runway at 260 knots, about twice the recommended speed, and called the tower to erect the emergency recovery net. The hook was torn away from the fuselage because of the high speed, but I managed to stop 10 meters before the net. I turned back to shake the hand of my instructor, who had urged me to eject, and then I saw it for the first time - no wing !!!
The IAF (Israeli Air Force) contacted McDonnell Douglas and asked for information about possibility to land an F-15 with one wing. MD replied that this is aerodynamically impossible, as confirmed by computer simulations... Then they received the photo.... After two months the same F-15 got a new wing and returned to action.

On 1 May 1983, during an Israeli Air Force training dogfight, an F-15D collided with an A-4 Skyhawk. Unknown to pilot Zivi Nedivi and his copilot, the right wing of the Eagle was sheared off roughly two feet (60 cm) from the fuselage. The F-15 entered an uncontrollable spin after the collision. Zivi decided to attempt recovery and engaged afterburner to increase speed, allowing him to regain control of the aircraft. The pilot was able to prevent stalling and maintain control because of the lift generated by the large horizontal surface area of the fuselage, the stabilators and remaining wing areas. The F-15 landed at twice the normal speed to maintain the necessary lift, and its tailhook was torn off completely during the landing. Zivi managed to bring his F-15 to a complete stop approximately 20 ft (6 m) from the end of the runway. He was later quoted as saying "(I) probably would have ejected if I knew what had happened
