Jonathan G. O'Neill was born on March 28, 1921 the son of Alpheus and Ethel O'Neill in Hartland, Niagara County in New York State to the north of Buffalo. Later, the family moved to the nearby town of Gasport, New York. His father was a World War I veteran who served in the U. S. Army Quartermaster Corps. He had two younger siblings: Paul N. O'Neill and Frances M. O'Neill. The children grew up on the family farm and helped raise chickens and cherries. In his youth, he was known as both "John" and "Johnny".
He graduated Lockport High School class of 1939 and was a member of school band and Hi-Y (a YMCA group). During the autumn of 1939, he enrolled in Cornell University class of 1943 and attended the college of agriculture until his sophomore year until the spring of 1941 when he enlisted in the U. S. Army. At age 19, O'Neill's profession was listed as a waiter in a restaurant in the U. S. Census of 1940. During the fall of 1940, O'Neill joined the first civilian pilot training program at Ithaca Airport and learned to fly and became a licensed pilot.
U. S. Army Air Force
At age 21, O'Neill enlisted in the U. S. Army Air Force (USAAF) as an Air Corps aviation cadet serial number 12030293. He was commissioned as a 2nd Lieutenant with serial number O-659837. He completed basic flight training at Randolph Field in Texas flying the PT-19, BT-9 and AT-6. Next, he completed advanced training at Moore Field in Texas. By May 1942, he had logged 200 hours of flight time before transitioning to the P-38 Lightning. Afterwards, stationed at Hamilton Field in California where he continued to fly the P-38 Lightning and befriended Richard Ira "Dick" Bong. The pair was nearly received a court-martial when Bong buzzed a friend's house and O'Neill flew under the Golden Gate Bridge at San Francisco. Instead, both were deployed overseas departing flying across the Pacific to Australia.
On August 29, 1942 O'Neill was flown overseas to Australia arriving on September 2. Assigned to the 5th Air Force as a fighter pilot, possibly attached to the 17th Provisional Squadron or 39th Fighter Squadron on a temporary basis.
During December 1942 he was flying P-38 training missions from Amberley Field west of Brisbane. On December 4, 1942 O'Neill survived an aerial collision on a training mission when P-38F "Synchronized Sal" 42-12646 piloted by 2nd Lt. Rowsey accidentally collided with his aircraft. Damaged, O'Neill managed to trim his P-38 to fly on one engine and made a safe landing. The other pilot 2nd Lt. Rowsey became caught on his own tail boom and died on impact.
O'Neill was assigned to the 49th Fighter Group, 9th Fighter Squadron "The Flying Knights". Assigned P-38G "Beautiful Lass" 43-2204
Squadron Number 99 and combat missions from 14 Mile Drome (Schwimmer) near Port Moresby then Horanda Airfield (Dobodura No. 4) and Kiriwina Airfield. He flew combat missions over New Guinea including Lae and Oro Bay plus missions over New Britain against Rabaul. He often flew combat missions with fellow pilots including: Richard I. Bong, Carl G. Planck, Jr. and Ralph H. Wandrey.
Aerial victory claims
O'Neill was officially credited with eight aerial victory claims against enemy fighter aircraft between March 4, 1943 to October 29, 1943. During a two week period between (October 15–29, 1943) O'Neill claimed six of his eight victories. On October 24, 1943 he became an "ace" with five aerial victory claims, the first World War II ace from New York State. All of his victory claims were against Japanese fighter aircraft in the air. In New Guinea, O'Neill earned the nickname 'Jump' because he was expert in jumping the enemy, shooting them down and avoiding their return fire. He was often photographed with a cigar.

March 28, 1943 – Victory over Oro Bay
On March 28, 1943 O'Neill took off piloting P-38G "Beautiful Lass" 43-2204 as one of eight P-38s on a mission to intercept Japanese bombers escorted by Zeros bound for Oro Bay.
October 24, 1943 – Double Victory Over Rabaul
On October 24, 1943 O'Neill took off piloting P-38G "Beautiful Lass" 43-2204 leading "Green Flight" on a mission over Rabaul. Over the target, he claimed his fifth and six victories as he and two other pilots dove down from 6,000' down onto three Zeros flying at 3,000'. He made several ineffective passes at one, finally shooting the entire tail off a Zero at a 45 degree deflection. Minutes later, he put another burst into a second Zero, causing it to fly straight and crash into a hill. Returning from the mission, O'Neill was photographed in the cockpit smoking a cigar and holding up five fingers indicating he had made ace.
October 29, 1943 – Double Victory Over Rabaul
On October 29, 1943 O'Neill claimed his seven and eight victories over Rabaul.
On November 7, 1943 O'Neill led the 9th Fighter Squadron on a combat mission to escort B-24 Liberators over Rabaul. He made no victory claims that mission. Lost was P-38G 43-2199 piloted by 2nd Lt. Stanley W. Johnson (MIA).
Return to the United States
On December 4, 1943 O' departed the South West Pacific Area (SWPA) across the Pacific returning to the United States two days later and returned home to Gasport, NY for three weeks of rest and recuperation, his first trip home since his enlistment in the U. S. Army. On December 21, 1943 he returned to Ithaca Airport to visit the Ithaca Flying Service where he learned to fly in 1940. Fellow pilot and friend Richard Ira "Dick" Bong accompanied him on the trip and the pair went on a War Bond tour in the United States.
In 1945, O'Neill's married Glow, who he met in California. One of the wedding guests was Richard Bong who attended incognito to avoid media hoopla. At the end of his service, assigned to the 440th Army Air Force Base Unit (440th AAFB). On September 17, 1945 O'Neill was discharged from Fort Dix, New Jersey.
O'Neill served between April 30, 1942 until September 17, 1945 including 2 years, 1 month and 10 day in the United States and one year, 3 months and seven days overseas. For his World War II service, O'Neill earned a Distinguished Flying Cross (DFC) with two clusters, Silver Star, Air Medal with oak leaf cluster (awarded by Lt. General George C. Kenney), Asiatic Pacific Theater campaign ribbon and American Theater campaign ribbon.
Silver Star citation: "First Lieutenant (Air Corps) John G. O'Neill (ASN: 0-659837), United States Army Air Forces, was awarded the Silver Star for gallantry in action against the enemy as a Fighter Pilot of the 9th Fighter Squadron, 49th Fighter Group, Fifth Air Force, in action against the enemy in aerial combat in the Pacific Theater of Action during World War II. His gallant actions and dedicated devotion to duty, without regard for his own life, were in keeping with the highest traditions of military service and reflect great credit upon himself, his unit, and the United States Army Air Forces." via Hall of Valor - John G. O'Neill - Silver Star
In a letter to his parents, Lt. General George C. Kenney C. O. 5th Air Force wrote about his award of the Air Medal with oak leaf cluster: "This award was made in recognition of his courageous, fearless service to his combat organization, his fellow American airmen, his country, his home and to you. Your son was decorated for meritorious achievement while participating in aerial fights in the Southwest Pacific area. Almost every hour of the day your son, and the sons of other Americans, are making a very real and very tangible contribution to a victory and to peace. I would like to tell you how genuinely proud I am to have men such as your son in my command, and how gratified I am to know that young Americans with such courage and resourcefulness are fighting our country's battle against the aggressor nations." via Lockport Union-Sun & Journal "Gasport Flier Gets 3rd Award" circa 1943.
In 1946, O'Neill started the first crop dusting service in Niagara County, New York. He married in 1951 and had two children: Margaret and Nancy, then divorced. In 1959 he married Dolores and had two children: Tracey and John.
He divorced and later married Dolores Arnold of Pennsylvania who was also a pilot and instructor. Later, the couple moved to Miami, Florida.
O'Neill passed away from leukemia at Veterans Hospital Miami, Florida on September 30, 1966 likely as a result of the pesticides used in his postwar crop dusting career. He is buried at Hartland Central Cemetery in Hartland, NY with two markers: a stone that reads: "Jonathan G O'Neill 1921–1966" and a military markers that reads: "John G. O'Neill New York Capt 440 Base Unit AAF World War II SS-DFC-AM March 28, 1921 Sept 30, 1966".
Jonathan O'Neill (son)
"In total, my dad had 4 kids. With his first wife (1951-58), he had my step-sisters, Margaret and Nancy (who now live in Virginia Beach). With my mom (1959-66), there was me and my sister, Tracey, who now lives in Lake Bluff, IL. I have always been interested in World War II, especially the Pacific,
because that is where my father flew. I had heard the stories about his combat exploits
since I was little. As
I got older, I found out more: that he was an ace; that he flew wing for Richard
Bong, America's top ace in World War II. Since I was about ten, I have read just
about everything I could get on the Pacific conflict. These
days, I am an editor at The Miami Herald. I also have a private pilot's license
and am a fairly experienced video and film editor. My father died from leukemia when i was six in 1966, so most of my knowledge of him comes from others, but they all seemed to think he was this larger than life kind of character. He had a brother, Paul, and a sister Frances, both still living. According to his fellow pilots, he was described as a helluva pilot, who had no fear.
They told that Bong had to get in very close to shoot, and that my dad was tucked right in there with him. When he married my mother (also a pilot) they moved to Miami, Florida where my sister and I were born. What snippets I do remember of him always revolved around flying. It was a common theme in the house, and I heard flying terms from the time I was born. I got my pilot's license when I was 20 - it seemed almost a natural thing to do."

"An Associated Press story written by Murlin Spencer from Allied Headquarters in the Southwest Pacific tells about men from New York State and the part they played in the second year  of the war in that area.
Capt. John G. O’Neill of Gasport, a member of the Class of 1943 at Cornell, attacking four bombers attempting to raid Oro Bay in New Guinea, and, picking out the leader, sent it crashing into the sea. Then with two Zeros on his tail he slashed into another formation of four Zeros to break it up. He has destroyed eight Jap planes to date, according to the Spencer story, and ‘it was O’Neill who went out and shot down four Japanese planes in three days after his buddy was killed. He is back in the states now.”

[Page 74] "Like McGuire, he [Wally Jordan] turned some people off, such as one of the squadron's old hands named 'Jump' O'Neil [sic]. O'Neil watched with chagrin as Wally beat him to Captain, something that Jump thought he deserved more than Wally did. After that, he would always address Wally as 'Captain' in a sneering, almost derisive tone. 'I don't know what that guy's problem was...,' recalled Wally years later."

Behind Jerry, Jump O'Neil was in trouble. Like Fanning, he couldn't get his [drop] tanks loose either, but he tried to stay with his flight mates as they waded into the Oscars. He immediately attracted unwanted attention and a Ki 43 slid behind him and gave chase. Jump put the nose down and firewalled the throttles, running flat-out away form the menace on his P-38. Finally after several minutes of this race, the Oscar fell behind and broke off the chase, giving Jump a chance to get rid of his"
[Page 100] tank. He finally got one loose, then ripped the other off in a dive, and he turned back towards the fight, climbing to 10,000 feet. After patrolling for several minutes without sighting the enemy, Jump called it a day and headed for home."
[Page 145] The Flying Knights returned to Rabaul on November 7 . This time, Captain Jump O'Neil [sic] led the squadron - or what was left of it. The outfit was down to eight flyable birds, and all were in bad shape. Among those flying with Jump that day were Dick Bong and Stanley Johnson."
