On 21 August 1961, the first supersonic flight by a civil airliner was achieved. A new world altitude record was set for civil airliners during the record-breaking flight. The aircraft involved in this milestone flight was a brand new Douglas DC-8-43 (c/n.45623), powered by Rolls Royce Conway engines. It was owned by Canadian Pacific and allocated the registration CF-CUD.

The world's first supersonic airliner — Douglas DC-8-43 (c/n.45623) CF-CUD of Canadian Pacific.

The record-breaking flight was conceived and commanded by Douglas test pilot Bill Magruder (who had co-piloted the first flight of the DC-8 prototype on 30 May 1958) and was carried out during the pre-delivery flight test program for the new airliner and with the permission of Canadian Pacific. The DC-8 was in completely standard trim (including standard airline interior) apart from some special test and recording equipment that was carried for the record-breaking flight.

The DC-8 took off from Long Beach, California and climbed to a new record altitude (for airliners) of 52,090 feet while positioning overhead Edwards Air Force Base (also in California). When all was ready, the thrust levers were advanced to bring the engines up to take-off power, then the nose was pitched down 30° and held at that attitude while the aeroplane dived and accelerated. At 41,088ft the aircraft reached supersonic speed and maintained Mach 1.012 to 36,000 feet where the nose was gently raised to 8° above the horizon and that attitude held (with the engines still at take-off thrust) until the aircraft decelerated back to subsonic speed. The airliner reached its highest true airspeed of 662.5 mph (1,066.2 km/h) just before the recovery from supersonic flight. Power was reduced to normal cruise thrust after the recovery and the airliner was flown back to Long Beach. The co-pilot was Paul Patten and flight test engineers were Joe Tomich and Richard Edwards.

Throughout the record-breaking run, the DC-8 was accompanied by two 'chase' planes, a F-104 Starfighter equipped with specially calibrated instruments and a F-100 Super Sabre from the USAF Flight Test Centre which acted as a camera ship. Ground tracking facilities were provided as the DC-8 performed its supersonic dive over the Askania Tracking Range at Edwards Air Force Base.

It is interesting to note that there was no airframe buffet during acceleration through the transonic region to supersonic flight, however some airframe buffet did occur during the deceleration period back to subsonic flight.

The flight carried a large number of special first-day airmail covers on the supersonic flight and these were transported to Edwards Air Force Base following the conclusion of the flight to be postmarked at the base Post Office.

An example of the world's first supersonic airmail.

The DC-8 suffered no ill effects from its historic flight and was delivered to Canadian Pacific shortly afterwards. During its career with the airline, the supersonic DC-8 logged more than 70,000 hours of flight before it was retired and sold for scrap in 1980.  The aircraft carried a special ‘supersonic’ insignia on its vertical tail throughout its service with Canadian Pacific.

Victor bomber accidentally becomes airborne during taxi demo

By DAVID KAMINSKI-MORROW - Flight International | Tuesday, May 05, 2009

UK air accident specialists are not intending to investigate an unusual incident at an air show during which a Handley Page Victor bomber unexpectedly became airborne during a high-speed taxi demonstration.

The incident occurred during the Cold War Jets Open Day at the Bruntingthorpe airfield, south of Leicester, the scene of the recent restoration to flight of an Avro Vulcan.

Bruntingthorpe's Victor, XM715, had been participating in the 3 May event when it became briefly airborne, apparently reaching a height — based on photographic evidence — of at least 20-30ft.

Circumstances of the incident are unclear. There are no confirmed details of the speed of the aircraft, the crew complement, or meteorological conditions, nor has it been confirmed whether the aircraft sustained any damage.

But while the Air Accidents Investigation Branch says it is "aware" of the incident, it is not conducting an inquiry. The Civil Aviation Authority has so far been unable to comment further, pending clarification of the incident, but says the aircraft is not on the civil register.

Bruntingthorpe's Cold War Jets event involves fast taxiing of several vintage aircraft including the de Havilland Comet, English Electric Lightning and Hawker Siddeley Buccaneer.

First flown in 1952 the Victor was, alongside the Vulcan and the Vickers Valiant, part of the Royal Air Force's nuclear deterrent ‘V-bomber’ fleet.

A Japan Airlines jetliner preparing to depart Los Angeles was grounded on Monday after one of the plane's jet engines apparently sucked up a cargo container, officials said.

Television footage showed the large object wedged into an engine as the plane sat on the tarmac at Los Angeles International Airport.

JAL Flight 61 had been leaving the gate at around 1.30pm (0630 AEST) when the unidentified object blocked one of the engines, according to Los Angeles World Airports, the agency which operates the airport.

The 245 passengers on board were transported back to the airport's Tom Bradley International Terminal. No one was injured.

An investigation was underway.

Indonesian plane crashes, at least 69 dead

Associated Press | 4:06PM NZST - Wednesday, 20 May 2009

69 DEAD in Indonesian plane crash. — Associated Press.

  69 DEAD in Indonesian plane crash. — Associated Press.

An Indonesian military plane carrying more than 100 people crashed into several homes and burst into flames Wednesday, killing at least 69 people, officials said.

Dozens of people were injured and more were feared dead, with local television flashing footage of fire engulfing the mangled wreckage and soldiers carrying bodies on stretchers. Some were badly burned.

Air force spokesman Bambang Sulistyo said the C-130 Hercules, carrying 112 passengers and crew, was on a routine training mission when it crashed near an air force base in East Java province. It smashed into four houses in Geplak village, before skidding into a rice field.

It was not clear what caused the crash, the latest in a string to hit the air force.

Several witnesses said the plane split apart in the air following a loud explosion.

"One of the wings fell off," Agus Yulianto, a villager, was quoted as saying on the Web site of Kompas newspaper. "Then the plane nose-dived into the houses."

The death toll stood at 69, said Suyono, a spokesman at the air force base, adding that he expected the number to climb.

Huge plumes of black smoke billowed from the scene and bystanders were seen throwing buckets of water and sand at the flames. Ambulances were shuttling victims to a nearby hospital.

The country's air force has long complained of being underfunded and handicapped by a recently lifted US ban on weapons sales. It has suffered a series of accidents, including a Fokker 27 plane that crashed into an airport hangar last month, killing all 24 onboard.

A series of commercial airline crashes in recent years has killed more than 120 people in Indonesia.

Jumbo to make final flight

NZPA | Friday, 05 May 2009

BYE BOEING: The 19-year-old jumbo jet was grounded and put up for sale after performing the airline's biofuel test flight in December.

BYE BOEING: The 19-year-old jumbo jet was grounded and put up for sale after performing the airline's biofuel test flight in December.

Air New Zealand's first Boeing 747-400 begins its long trip to the scrapheap today, departing Auckland for the United States to be dismantled for parts.

Already stripped of its seats and furniture ZK-NBS was scheduled for take off at 5.20pm bound for Roswell, New Mexico.

"The final flight of NBS is a sad and very visible example of the effects of the economic downturn on Air New Zealand," airline spokesman Ed Sims said.

The 19-year-old jumbo jet was grounded and put up for sale after performing the airline's biofuel test flight in December.

"We are seeing long-haul demand down more than 10 percent," Mr Sims said.

"We are very focused on ensuring capacity closely meets demand and are utilising the more fuel-efficient 777 fleet as much as possible to reduce long-haul fuel costs."

After arriving in Auckland from Boeing's Seattle factory in December 1989, NBS completed more than 11,400 flights.

It spent 88,300 hours (more than 10 years) in the air and travelled an estimated 80 million kilometres (the equivalent of 100 round trips to the moon or more than 2000 return trips to London).

Last Monday (27th July) was the 60th anniversary of the first flight of the prototype of the world's first jet airliner — the de Havilland DH.106 Comet.

Although the Comet suffered from a few problems caused by pushing the envelope too far too fast in accordance with the then knowlege about high speed, high altitude pressurised aeroplanes, the Comet began a revolution in air travel that it shared with another British gas turbine powered aeroplane, the Vickers Viscount, and opened the door to the cheap, mass air transport we all benefit from today.
