Rising to as high as 20,000 feet (6,096 m), he is swept backward out over the Atlantic Ocean and disappears about eight hours after takeoff. Some of his balloons are found floating intact in the sea two days later, and his body will be found floating in the Atlantic 700 km (435 mi) northeast of Paranagua near Maricá, Brazil, on 4 July.

The Navy report states in part: "The cause of this tragic accident was the failure of the pilot to manage the energy state of the aircraft, and then to recognize a departure from controlled flight at low altitude, and apply the NATOPS recovery techniques." This Phantom II was credited with a MiG-17 kill 10 May 1972 with VF-96.

Both crews escape in each plane's two-seat crew ejection modules. Flotation bags on the Peluso/Schlitt module became partially dislodged soon after landing and the module submerged under several feet of water. The other crew module became inverted immediately after hitting the water and remained inverted on the water's surface until the arrival of a fishing vessel. At that time the crew activated self-righting bags that partially righted the module. The crew then exited the module and, assisted by a RAF rescue parajumper, climbed aboard the fishing vessel before being hoisted to a RAF rescue helicopter. The fishing vessel arrived in the area of the crew modules approximately 40 minutes after the collision, with the rescue helicopter from RAF Lossiemouth arriving several minutes later. A Nimrod maritime patrol plane monitored from overhead. All four crew were flown by helicopter to RAF Lossiemouth, 40 miles NE of Inverness. All four returned to Lakenheath later that day. They were identified as Capt. Stephen R. Ruttman, of Norman, Oklahoma, Capt. Timothy A. Schlitt, of Afton, Missouri, Capt. Roger L. Webb, of Staunton, Virginia, and Capt. Joseph Peluso, of Rosedale, New York, all of them 28.

Ritchie had departed Kirtland after refuelling for March AFB, California, but due to apparent engine failure on take-off, the fighter never rose above 25 feet, skidded off end of runway, cartwheeled across an arroyo, and broke apart but did not burn.
