On the morning of March 10, 1967, Captain Bob Pardo looked out the left side of his F-4 Phantom cockpit at another F-4 Phantom that was about to stop flying. The second jet belonged to his wingman, Captain Earl Aman, and it was bleeding fuel from a hole the size of a melon. They were over Laos, still 88 miles short of the nearest friendly airfield, and Aman’s F-4 had enough fuel to fall out of the sky in about three minutes.

Pardo had a decision to make in the time it took him to breathe twice. He could do what the rulebook said — climb away, call search and rescue, and watch two friends eject over a jungle they might not walk out of. Or he could try something no one had ever tried before. He chose the second thing. What happened next is one of the strangest, most improbable rescues in the history of combat aviation.

The Steel Mill That Wouldn’t Die

The Thai Nguyen iron and steel works sat 40 miles north of Hanoi and produced something like 200,000 tons of steel a year for the North Vietnamese war effort. American planners had been trying to knock it down for months. The complex was ringed by anti-aircraft artillery and surface-to-air missiles, and every strike package that went in came out with casualties.

On March 10, Pardo and Aman were flying in a four-ship of F-4Cs escorting F-105 Thunderchiefs on the bombing run. They launched from Ubon Royal Thai Air Force Base, refueled over Laos, crossed into North Vietnamese airspace with dread in their chests and Rolling Thunder on the radio. The flak coming up to meet them was, by every account of that day, as thick as any ever seen in the war.

Aman’s aircraft took a hit from 85-millimeter anti-aircraft fire somewhere over the target. A fuel line ruptured. Pardo’s jet took hits too, less severe, and both pilots continued the run — American fighter pilots did not turn around over Hanoi unless the aircraft had stopped working. They rolled in, dropped their ordnance, and turned for the border.

Three Minutes of Fuel

It was during the egress, several minutes after the bomb run, that Aman finally called it in. His fuel was going. The leak was big enough that the tanker couldn’t save him — he would flame out on the boom. He was going to have to eject over North Vietnam, and in March of 1967 that meant the Hanoi Hilton, or it meant death.

Pardo slid his Phantom alongside Aman’s. He looked across at Bob Houghton in the back seat, then at Aman up front. He later told interviewers he could see the math on both men’s faces. They had done it. They had accepted it. They were going to eject and take their chances.

Pardo’s back-seater, 1st Lt. Steve Wayne, suggested something insane over the intercom. What if we pushed them?

The idea was not unheard of. In the F-4 community there had been quiet talk, mostly over drinks, about whether one jet could mechanically push another. In principle, yes: if you could rest one airframe on top of another and match thrust, the two aircraft would form a single ungainly creature that could technically fly. In practice, nobody had tried it. Nobody had any idea if it would actually work.

The First Attempt: Drogue Chute

Pardo tried it first with Aman’s drag chute. The idea was to pop Aman’s drogue, then fly his own Phantom’s nose into the trailing chute, letting it cushion and distribute the contact load. It didn’t work. The drogue chute fouled on Pardo’s canopy almost immediately. Scratch plan A.

Pardo thought about it for another few seconds. Then he had an idea that was either brilliant or suicidal, depending on your point of view. The tail hook. The F-4 had a large steel tail hook under the fuselage for emergency arrested landings. If Aman lowered his hook, Pardo could slide his own F-4 forward until the hook rested against his windscreen frame. The two jets would be mechanically linked, nose-to-tail-hook, and Pardo’s thrust could push Aman’s dying aircraft through the sky.

He called the plan over the radio. Aman lowered his hook.

88 Miles of Nerve

The geometry was terrible. Pardo had to fly his F-4’s windscreen — a curved piece of armoured glass worth a year’s pay — directly into a steel hook trailing from another aircraft moving at 300 knots, and then hold it there. Every pocket of turbulence, every twitch of Aman’s controls, every flex of the air between them tried to separate the two jets. When the hook slipped off the windscreen, which it did repeatedly, Pardo had to re-align and try again. And again. And again.

He eventually figured out that the best contact point was the windscreen frame itself, a small flat pad of metal on the Phantom’s nose that could take the pressure. When Aman’s engines finally flamed out from fuel starvation, Pardo was still pushing. Aman became a 58,000-pound dead-weight glider. Pardo’s single-aircraft thrust now had to keep both of them in the air.

They lost altitude constantly. The hook slipped off the windscreen every thirty seconds. Pardo kept re-contacting. Aman and Houghton sat in a silent Phantom with no engines, watching the Laotian jungle come up underneath them. The radios were quiet because there was nothing to say.

They covered 88 miles like that — roughly ten minutes of continuous contact, with breaks only when Pardo had to re-align. Ten minutes is not a long time. Unless you are trying to hold two fighter jets together with a tail hook and a windscreen.

Ejection

Pardo’s own fuel was now running out. Both aircraft were burning hydraulic fluid. They were over Laos — friendly territory for the purposes of rescue — and Pardo finally called it. He broke contact. Aman and Houghton punched out first. Pardo and Wayne went seconds later. All four parachutes blossomed over the jungle.

A U.S. Air Force HH-3 Jolly Green Giant rescue helicopter picked them up within the hour. Every one of them walked out alive.

A Silver Star, 22 Years Late

Here is the part that tells you everything about the Air Force of 1967. When Pardo got back to Ubon, he was reprimanded. Not formally punished, but told — clearly — that he had risked and effectively lost a valuable airframe in a manoeuvre that was not in any manual. The Air Force lost two Phantoms that day instead of one. On paper, that was the wrong outcome.

Nobody at the squadron disagreed with Pardo. Everybody at the Pentagon did. The rescue did not get written up for a medal, because there was no template for the kind of flying that had been done. It sat in Pardo’s file as a footnote.

It took twenty-two years. In 1989, after repeated lobbying by Pardo’s fellow pilots and aviation historians who had finally pieced the story together, the Air Force quietly awarded Bob Pardo and Steve Wayne the Silver Star for their actions on March 10, 1967. By then Pardo was a retired lieutenant colonel running an air freight company. Aman had died of ALS in 1998. Wayne received his in person.

In interviews later in life, Pardo was characteristically brief about what he had done. He didn’t think he had been heroic. He thought he had been a guy with a good idea at a bad moment, trying not to leave two friends in the jungle. His back-seater Steve Wayne, when asked years later whether he had really thought it would work, shrugged. “It worked once,” he said. “That was enough.”
