|Maynard Hill, a designer of model airplanes who secured a spot in aviation history in 2003 when one of his creations flew 1,882 miles across the Atlantic Ocean on less than a gallon of fuel, died June 7 of prostate cancer at his home in Silver Spring. He was 85.
A balsa-and-glue virtuoso, Mr. Hill was a legend in the model-aircraft world even before his first-of-its-kind transatlantic feat. Beginning in the 1960s, he set 25 world records for speed, duration and altitude, flying his radio-controlled aircraft as high as 26,990 feet, as long as 38 hours and as fast as 151 mph.
Professionally, Mr. Hill was a metallurgist at the Johns Hopkins University Applied Physics Laboratory who eventually convinced his supervisors that he should be allowed to indulge his hobby at work. He became a pioneer in developing unmanned aerial vehicles - drones - for the military.
He was retired, legally blind as a result of macular degeneration and mostly deaf in the 1990s when he announced at a meeting of the D.C. Radio Control Club that he intended to fly a model airplane across the Atlantic - from the Canadian province of Newfoundland to Ireland.
With the exception of Mr. Hill, no one thought it was possible. According to international rules, a plane must weigh less than 11 pounds - including fuel - to qualify as a model. No such plane had flown even one-third as far as Mr. Hill was proposing.
Nevertheless, a group of other retired engineers and computer programmers soon joined the mission, swayed by Mr. Hill's optimism and track record.
Working in his basement shop with the aid of special glasses and glue dyed red for better visibility, Mr. Hill perfected a tiny four-stroke engine that ran on camp-stove fuel, sipping just two ounces per hour. He mounted it on a balsa and Mylar skeleton with a six-foot wingspan. He did this over and over, building 29 versions of his design - the first 24 of which failed, crashed or disappeared in flight.
|Meanwhile, Mr. Hill's team helped raise tens of thousands of dollars. It perfected a computerized autopilot system to guide the aircraft on its long journey. And crew members flew Mr. Hill's prototypes on countless test flights at a Montgomery County horse farm owned by Beecher Butts, an octogenarian aviation enthusiast.
In 2002, after four years of full-time work, the team traveled to Cape Spear, Newfoundland, for a first transatlantic attempt.
It was a disaster. Three planes went in the drink, two of them after traveling less than 30 miles. The computer experts on the team discovered a fundamental flaw in the navigational software.
Mr. Hill, undaunted, urged everyone - including his wife, who had driven a rental van for six days to deliver her husband and four airplanes to the launch site - not to give up.
After 12 more months of tinkering, the team returned to Canada. Mr. Hill threw his 25th plane, javelin-like, toward the east.
A tiny computer in the plane's innards relayed information about its location and altitude. It behaved oddly, dipping and rising in an unpredictable fashion and at one point failing to communicate its position for three hours.
|Mr. Hill heard news of the landing by phone. Less than two ounces of fuel - a whiskey shot's worth - remained in the plane's tank. "I just grabbed my wife, hugged her and cried like a baby," he said. "I'm an emotional guy."
Maynard Luther Hill was born Feb. 21, 1926, in the Pennsylvania coal town of Lehighton. He grew up admiring Charles Lindbergh and Amelia Earhart but was always more fascinated by tiny airplanes than their full-sized counterparts.
"By age 9," he once wrote, "I had acquired a fairly serious addiction to balsa wood and glue."
He joined the Navy after graduating from high school in 1943 and served in Panama during World War II.
After the war, Mr. Hill earned bachelor's and master's degrees, both in metallurgy, from Pennsylvania State University.
He was singing in a choir at Penn State when he met Gay Brunner, a fellow singer. They were married in 1951. On Day 3 of their honeymoon, he later said, "I told my wife I just had to go out and get some balsa and glue."
|Besides his wife of 59 years, survivors include three children, Christopher H. Hill of Santa Fe, N.M., Vivian Snipes of Lexington, Ky., and M. Scott Hill of Hurlock, Md.; a brother; a sister; and 10 grandchildren.
Mr. Hill was inducted into the Model Aviation Hall of Fame in 1977. Several of his planes, including the Spirit of Butts Farm, are on display at the National Model Aviation Museum in Muncie, Ind. Another plane, a backup for the transatlantic effort, is in the National Air and Space Museum's collection.
"It used to be we said we wanted to be famous," Mr. Hill told The Washington Post in 2001, in the midst of his five-year marathon effort to build an ocean-crossing plane. "Now, it's just the actual joy of putting it together and making it work and knowing that you had the brains to do all that."
