The doctor who came to Harrison Ford's aid immediately after seeing his plane crash-land on a Los Angeles golf course says he was stunned to discover the actor at the controls.
Dr Sanjay Kahurana was golfing when he saw the plane "drop like a rock" about 50 yards in front of him.
He ran to the plane and found the pilot stunned and complaining of pain below his waist and with a deep gash in his scalp.
Dr Kahurana and other golfers pulled him from the wreckage and the doctor assessed his condition.
It was at that point that Dr Kahurana realised who he was treating.
Ford is in hospital with undisclosed injuries that his publicist says are not life-threatening.
The National Transportation Safety Board is investigating.
The actor, who battled Hitler's henchmen in Raiders Of The Lost Ark as dashing archaeologist Indiana Jones, was flying a World War II-era plane when it lost engine power shortly after take-off from Santa Monica Municipal Airport near Los Angeles.
"He had no other choice but to make an emergency landing, which he did safely," Ford spokeswoman Ina Treciokas said.
Ford's son Ben tweeted from the hospital: "Dad is ok. Battered, but ok! He is every bit the man you would think he is. He is an incredibly strong man."
Ford had a cut to his forehead and scraped arms, but it was not clear what internal injuries he may have received, Los Angeles assistant fire chief Patrick Butler said.
"He wasn't a bloody mess. He was alert," Mr Butler said.
Ford told the airport tower about 20 minutes after his 2pm take-off that he had engine failure and was making an immediate return, according to a recording.
The plane had been flying at about 3,000 feet (914 metres) and hit a tree on the way down, according to witnesses and officials.
The plane, a yellow 1942 Ryan Aeronautical ST3KR, had damage mostly confined to the front.
"I would say that this is an absolutely beautifully executed - what we would call - a forced or emergency landing, by an unbelievably well-trained pilot," said Christian Fry of the Santa Monica Airport Association.
Charlie Thomson, a flight instructor at the airport who saw Ford take off, said engine failure like Ford's does not make the plane harder to manoeuvre.
"It just means you have to go down," he said.
The airport's single runway sits amid residential neighborhoods, and city leaders and many residents advocate closing it, citing noise and safety concerns.
Other planes have crashed into homes, and four people died in September 2013 when their small jet veered into a hangar and caught fire.
Ford, who plays the swashbuckling Hans Solo in his fourth Star Wars movie set for release in December, shuns attention to his private life but has been publicly effusive about his love of flying.
Ford got his pilot's licence in the 1990s and has made headlines, though he had never been significantly injured. In 2001, he rescued a missing Boy Scout with his helicopter.
Nearly a year before, he rescued an ailing mountain climber in Wyoming.
In 2000, a gust of wind sent a six-seat plane Ford was piloting off a runway in Lincoln, Nebraska. He and his passenger were not injured.
He has also volunteered his services during forest-fire season, when helicopters are busy battling blazes.
The National Transportation Safety Board investigation could take up to a year before a final report. NTSB investigator Patrick Jones said the agency would look at "everything: weather, man, the machine".
Ford last year wrapped Star Wars: The Force Awakens, which was briefly suspended when Ford suffered a broken leg during shooting.
He co-stars in a romance fantasy, The Age Of Adaline, due out April 24.
