UPDATE: DALLAS (ATHENS BANNER HERALD) — Glenn Smith left a lucrative job at a Dallas-area technology firm for an early retirement of restoring Soviet fighter jets and flying to exhibitions across the country.
He died Saturday when his nearly 30-year-old training plane nosedived during an air show in eastern Iowa and crashed into a field, authorities said. Spectators watched the 59-year-old Smith's plane erupt into flames, followed by a cloud of gray smoke. Nobody on the ground was hurt.
Smith had been flying in formation with other members of the HopperFlight team at the Quad-City Air Show in Davenport.
The National Transportation Safety Board is investigating the crash. Senior air safety investigator Aaron Sauer said Sunday that a preliminary report on the crash is expected within a week, but a final report will likely take several months.
He said inspectors would examine the few remaining pieces of the plane, as well as Smith's autopsy and toxicology reports.
Smith did not make a mayday call or suggest any sign of distress before the crash, according to Sauer and Randy Ball, a good friend of Smith's.
Ball said Smith was a meticulous flier who would map every step of a flight plan beforehand.
"They practiced the day before and everything went fine," Ball said.
Smith was a longtime technology entrepreneur whose company was acquired by Tyler Technologies, a Dallas-based company that develops software for local schools and government clients, in 1998. He remained an executive at Tyler until 2006, the company said in a statement.
After retirement, Smith focused on collecting and flying vintage planes. He kept two rare Soviet MiG-17 fighter jets at the Historic Aviation Memorial Museum in Tyler, about 90 miles east of Dallas, museum president Carolyn Verver said.
Ball, who also owns a MiG-17, said he spent countless hours working on planes with Smith. Smith loved to preserve planes so others could see and appreciate them, Ball said.
"Those guys are literally using their own money to save a part of history and share that history with everybody else," he said.
Smith was also the newest member of the "Hoppers," according to the team's website. The Hoppers are a group of pilots who privately maintain and fly L-39 fighter jets at air shows and other exhibitions. The L-39 Smith flew Saturday was made by a company in the former Czechoslovakia in 1984, according to a Federal Aviation Administration registry.
"He kept it absolutely immaculate," Ball said.
Part of the Hoppers' mission is to introduce American audiences to planes produced and used by the country's former enemies, according to the website.
"It is important for people to remember and for young kids to learn, so that history does not repeat itself," the website said.
According to the HopperFlight site, Smith had been a pilot for a quarter-century and has a commercial pilot's license with an additional instrument rating certification. Details about Smith's flight history from the FAA were not immediately available Sunday.
A squadron of planes flew over the crash site Sunday in the "missing man" formation before the air show continued.
(CNN) -- A plane performing at an air show in Davenport, Iowa, crashed and exploded in front of thousands of spectators.
The pilot of the plane was killed in the accident Saturday afternoon when the plane nosedived into an alfalfa field during the Quad City Air Show, officials said.
The pilot, who died on impact, was not immediately identified by authorities.
The plane, a high performance L-39 Albatross jet trainer, was attempting a 45-degree bank when it crashed, Assistant Police Chief Don Schaeffer told CNN affiliate WQAD.
The pilot was a member of the Hopper Flight, a group of exhibition fliers, Schaeffer said.
A home video taken by a spectator showed what appeared to be three airplanes flying in formation when one appeared to experience a problem.
Seconds later, the plane hit the ground and exploded in a giant fireball.
"Ladies and gentlemen, please keep your seats," an announcer can be heard saying on the video obtained by CNN affiliate KWQC.
"We have training and personnel on board to handle these situations."
The crash is under investigation by the Federal Aviation Administration and the National Transportation Safety, officials said.
The air show was temporarily halted after the crash, with "Taps" being sounded as aircraft flew in formation over the crowd.
The crash occurred just days after federal investigators released their findings behind the cause of a crash last September at the National Championship Air Races in Reno, Nevada, that killed a pilot and 10 spectators. More than 60 others were injured in the crash.
Investigators found that unprecedented speed and worn aircraft parts were behind the accident.
