In a blockbuster world exclusive, RadarOnline.com has obtained a secret government report detailing the terrifying, near-fatal catastrophe in 1992.
"The threat of a midair collision was very real," determined a National Transportation Safety Board review. Another source told Radar: "We definitely held our breath!"
The heart-stopping emergency unfolded in November 1992 when the actor's Gulfstream II jet suddenly lost electrical power at 30,000 feet.
Immediately, the plane's cockpit was plunged into total darkness and its safety systems, including radio and radar, were knocked out.
The "Saturday Night Fever" star was piloting his wife, Kelly Preston, their now-deceased son, Jett, and two friends from Florida to Maine.
But Radar has previously reported, the actor, 64, has used his private planes to feed his bottomless lust for gay sex, including flying nearly a dozen male lovers on a transglobal orgy!
During the in-flight emergency, the NTSB report suggested John played the hero, transmitting a distress call just before the blackout.
An air controller then directed the pilot of a nearby USAir Flight, which carried 182 passengers, to help locate the star's plane.
"He won't be lit up, so keep an eye out for him," the controller said, according to the NTSB records.
The report continued: "The controller then pointed the aircraft out at 12 o'clock and three miles. The pilot of USAir 1729 said, 'Yeah, he's coming toward us.'"
Radar tracked down the USAir pilot, Capt. Jeff Hightower, who recalled the chilling near-miss in detail.
"You want to help other people out, but he didn't have any lights," he said.
"It's like driving into a head-on collision. It didn't make any sense. What were we going to do, lead these guys down through the clouds?
"After air traffic control came on and told us we'd passed them, I remember thinking, 'Let's get the hell out of here!'"
