Gepard, can you find that article?
I've actually been researching this and can find absolutely no evidence to support it.
There is one exception from that time (Joel Aranoff) but his story is unique in the fact that he was Jewish, flew three tours in Vietnam as a USAF Phantom pilot, volunteered for a fourth and was denied, resigned his commission, immigrated to Israel and became a citizen, applied to the IAF and was accepted - the very first and something of a gamble for the Israelis who figured it might be worth it to have his experience while they were standing up their Phantom squadrons - and then flew in the Yom Kippur War. Joel didn't remain in the IAF or Israel, his career wasn't completely successful (apparently due to not mastering Hebrew) and he ended up returning to the US after some years. There were also a handful of US veteran helicopter pilots who may have flown during that time but I'm having a very difficult time tracking anything about them.
Joel Aranoff's story might give the "Americans in the IAF" story its beginning, but Americans were not pulled from active squadrons and thrown into combat against Egypt or Syria.
Here is an excerpt from something I've been working on:
In 1973 the IAF is accused by Egypt and Syria of having Americans in the cockpit due to the change in flying style they noticed. In reality it was the IAF recognizing that its tactics weren’t working, and the entire IAF was able to pivot on its heels and quickly adopt new tactics which enabled survival in the worlds densest Air Defense system. [cit. On Flexibility] During the war Americans did fly combat jets to Israel. Like the Soviet union supplying the Arab militaries, the US finally began to supply Israel with materiel, including aircraft. Desperately needed were A-4s and F-4s which had suffered terrible losses to modern Soviet-made SAMs and AAA, especially during the first few days of the war.
“Almost a hundred F-4s from Air Force units headed east to join the Israelis. More Navy Phantoms soon followed. A half dozen Israeli pilots arrived at Miramar three days after Mugs got orders to give up the shop’s A-4s. A serious, secretive bunch, the Israeli pilots expressed profound gratitude for the help. The Israelis flew the Topgun A-4s across the country and crossed the Atlantic, tanking en route before stopping in Portugal or Spain. For the American crews who delivered aircraft straight to Tel Nof, they discover not just an air force at war, but an entire people. The families of the flight crews lived in tents around the runways. Wives hung laundry out to dry next to missile batteries. Their country and lives were threatened. There could be no greater stakes for any patriot. The dynamics of the situation were so very different from the Vietnam War. More than a few of the U.S. pilots would have gladly stayed and flown into combat with the Israelis.” [Topgun: An American Story by Dan Pedersen]
Dan’s assertion that American pilots wanted to stay and fight is backed up by the memories of others:
“Chesterman said the Israelis welcomed the American pilots with a friendly meal on base, during which he and his fellow pilots “did our best to drink all their booze.” One of the Israeli pilots who had been drinking with them suddenly excused himself, saying he needed to return to the war. Only then did the Americans realize he had been drinking iced tea, not beer.
“Segars – the pilot who “fired at Muammar Gaddafi,” as Chesterman put it – earnestly tried to convince the Israelis to let him join the battle. But the several beers he had just downed “disabused him of opportunity to go fight in someone else’s war, Chesterman said.” [ https://www.timesofisrael.com/us-pilots-reunite-with-israeli-brothers-in-arms-from-yom-kippur-war/ ]
Segars - and any other American volunteer - would have certainly been declined even if they hadn’t been drinking. The Israeli’s had developed a unique and distinctive method of aerial warfare and throwing a pilot who isn’t used to such methods into such an environment would at best end with confusion. Israeli pilots in the heat of battle would be unlikely to be able to communicate with a non-Hebrew speaking American who was as unfamiliar with the battle space as he was the language.
