NEWS Bombardier CS100 completed test flights to 5.5-degree London City approach

Bombardier capped a series of CS100 tests at London City Airport (LCY) with a nonstop transatlantic flight to New York JFK on March 25, demonstrating the range capability of the smallest CSeries airliner from the airport closest to central London.

CS100 flight-test aircraft FTV2 completed eight flights from LCY over two days on Mach 22-23, to validate the aircraft’s ability to operate into the airport, with its 5.5-degree approach and short runway.

The flights, some with Transport Canada and European Aviation Safety Agency pilots on board, followed “hundreds” of landings in tests at Wichita and Salina, Kansas, Bombardier CSeries-VP and GM Rob Dewar said.

NEWS Two girls barred from United flight for wearing leggings

File picture

A United Airlines gate agent barred two girls from boarding a flight Sunday morning because the girls were wearing leggings.

Another girl who was wearing gray leggings had to change before she was allowed to board the flight from Denver to Minneapolis, a witness said.

The airline’s passenger contract says for the safety of all passengers and crew members, the airline can refuse to let a passenger board if the passenger is “barefoot or not properly clothed.”

United statement about the incident:

Let us take a moment to explain today’s news:

We care about the way we present ourselves to you, our customers, as we believe that is part of the experience on board our flights. One of the benefits of working for an airline is that our employees are able to travel the world. Even better, they can extend this privilege to a select number of what we call “pass riders.” These are relatives or friends who also receive the benefit of free or heavily discounted air travel – on our airline as well as on airlines around the world where we have mutual agreements in place for employees and pass riders.

When taking advantage of this benefit, all employees and pass riders are considered representatives of United. And like most companies, we have a dress code that we ask employees and pass riders to follow. The passengers this morning were United pass riders and not in compliance with our dress code for company benefit travel. We regularly remind our employees that when they place a family member or friend on a flight for free as a standby passenger, they need to follow our dress code.

To our regular customers, your leggings are welcome.

EMERGENCY Air Canada Dreamliner #AC17 shut down engine in flight and returned to Montreal

An Air Canada flight headed for Shanghai was forced to make an emergency landing shortly after taking off from Trudeau airport on Saturday.

Passengers onboard flight #AC17 reported hearing unusual sounds as the plane pulled away from the tarmac.

A warning light came on in the cockpit of the Boeing 787. The crew, following emergency procedures, shut down the engine, dumped fuel and contacted emergency teams on the ground.

“Our technical team will proceed with an inspection of the engine to determine the cause of the incident,” said Isabelle Arthur, a spokesperson for Air Canada.

#OnThisDay in 1977, KLM Flight 4805 collides with Pan Am Flight 1736 at Tenerife Los Rodeos Airport

40 years ago today, KLM Flight 4805 (PH-BUF) was a scheduled passenger flight from Amsterdam Schiphol Airport, Netherlands to Las Palmas de Gran Canaria Airport, Canary Islands. The Boeing 747-206B named Rijn (Rhine) was carrying 234 passengers & 14 crew members. 

PH-BUF, the accident aircraft involved.

The second aircraft involved, Pan American World Airways Flight 1736 (N736PA) was a scheduled passenger flight from Los Angeles International Airport to Las Palmas de Gran Canaria Airport, Canary Islands. The Boeing 747-121 named Clipper Victor was carrying 380 passengers & 16 crew members. 

N736PA, the accident aircraft involved. 


The cockpit crew of KLM Flight 4805 consisted of Captain Jacob Veldhuyzen van Zanten, First Officer Klaas Meurs, and Flight Engineer Willem Schreuder. Captain van Zanten was KLM’s most experienced pilot. He was featured in an advertisement in the KLM magazine Holland Herald. The magazines with this ad inside were on board KLM Flight 4805.

The cockpit crew of Pan Am Flight 1736 consisted of Captain Victor Grubbs, First Officer Robert Bragg and First Engineer George Warns. Seven years before this accident, N736PA was the first Boeing 747 to be hijacked.

At 12:30 pm a bomb planted by the CIIM terrorists exploded in a florist shop at Las Palmas de Gran Canaria Airport. 8 people were injured. Members then threatened to explode a second bomb at the airport, forcing police to shut down ATC while they searched for the bomb. A large number of flights were diverted to Los Rodeos Airport including KLM Flight 4805 and Pan Am Flight 1736. The airport had only one runway and one major taxiway parallel to it, with four short taxiways connecting the two.

While waiting for Las Palmas to reopen, the diverted aircraft took up so much space that they were parked on the long taxiway, meaning that it could not be used for taxiing. Instead, departing aircraft had to taxi along the runway to position themselves for takeoff, a procedure known as a runway backtrack. The KLM Flight 4805 passengers were transported to the airport terminal. While the Pan Am Flight 1736 passengers remained on board due to the terminal being full. Pan Am Flight 1736 passengers walked on the airstairs to stretch their legs.

At 15:00, Las Palmas Airport reopened, passenger Robina van Lanschot of KLM Flight 4805, who lived on the island, chose not to re-board KLM Flight 4805. Since the Pan Am Flight 1736 passengers remained on board it was possible to leave Tenerife at once. The taxiways were congested by other aircraft. This meant the Pan Am crew had to backtrack on runway 12 and takeoff on runway 30. The entrance to runway 12 was blocked by KLM Flight 4805. The Pan Am Flight had to wait almost 2 hours for all KLM passengers (except 1) had reboarded & refueling had taken place.

The KLM flight was then cleared to backtrack runway 12 and make an 180 degree turn at the end. Three minutes later (at 17:02) Pan Am Flight 1736 was cleared to follow the KLM aircraft and backtrack runway 12. The Pan Am crew were told to leave the runway at the third taxiway and report leaving the runway. During taxi onto the runway, the weather deteriorated & a fog bank rolled onto the runway limiting visibility. At 17:05:44 KLM 4805 reported ready for takeoff and was given instructions for a Papa beacon departure. The KLM crew repeated the instructions and added “We are now at takeoff”. The brakes were released and KLM Flight 4805 started the takeoff roll.

Tenerife tower, knowing that Pan Am Flight 1736 was still taxiing down the runway replied “OK …… Stand by for takeoff, I will call you.” This message coincided with the Pan Am crew’s transmission “No … uh we’re still taxiing down the runway, the Clipper 1736”. These communications caused a shrill noise in the KLM cockpit, lasting approx. 3.74 seconds. Tenerife tower replied: “Papa Alpha 1736 report runway clear.”, whereupon the PanAm crew replied: “OK, will report when we’re clear”. This caused some concerns with the KLM Flight engineer asking the captain: “Is he not clear then?” After repeating his question the captain answers emphatically: “Oh, yes”.

This caused some concerns with the KLM Flight engineer asking the captain: “Is he not clear then?” After repeating his question the captain answers emphatically: “Oh, yes”.

A number of second before impact, the KLM crew saw the Pan Am Boeing 747 still taxiing down the runway. The crew tried to climb away and became airborne after a 65 feet tail drag in an excessive rotation. The Pan Am crew immediately turned the aircraft to the left and applied full power. The KLM aircraft was airborne, but the fuselage skidded over the Pan Am’s aft fuselage, destroying it and shearing off the tail. The KLM aircraft flew on and crashed out of control 150 m further on, sliding another 300 m bursting into flames. Killing all 248 on the KLM aircraft. In total 583 passengers & crew lost their lives. Only 61 survived. It is the deadliest aviation disaster in history.


The accident was investigated by Spain’s Comisión de Investigación de Accidentes e Incidentes de Aviación Civil (CIAIAC) & assisted by the National Transportation Safety Board (NTSB).

The probable cause was that Captain Veldhuyzen van Zanten took off without clearance. The investigators suggested the reason for this was a desire to leave as soon as possible in order to comply with KLM’s duty-time regulations, and before the weather deteriorated further.

Other major factors contributing to the accident were:

  • The sudden fog greatly limited visibility. The control tower and the crews of both planes were unable to see one another.
  • Interference from simultaneous radio transmissions, with the result, that it was difficult to hear the message.

Other factors that were considered contributing but not critical were:

  • Use of ambiguous non-standard phrases by the KLM co-pilot (“We’re at take off”) and the Tenerife control tower (“OK”).
  • The Pan Am aircraft had not exited the runway at C-3. However, the angle of the third taxiway would have required the plane to perform a turn of approximately 148 degrees, which would lead back towards the still-crowded main apron. At the end of C-3, the Pan Am would have to make another 148-degree turn in order to continue taxiing towards the start of the runway. This would be extremely difficult for the Boeing 747 to do. Taxiway C-4 would only require two 35 degree turns.
  • The airport was forced to accommodate a great number of large aircraft due to rerouting from a bomb threat, resulting in disruption of the normal use of taxiways.

The Dutch authorities were reluctant to accept the Spanish report blaming the KLM captain for the accident. The Netherlands Department of Civil Aviation published a response that, while accepting that the KLM aircraft had taken off “prematurely”, argued that he alone should not be blamed for the “mutual misunderstanding” that occurred between the controller and the KLM crew, and that limitations of using radio as a means of communication should have been given greater consideration.

NEWS Satellite Eutelsat 172B is blocked in an Antonov An-124 at Cayenne Airport, Guyana

The first all-electric satellite in Europe has been blocked for several days in a container at Cayenne Airport, in Guyana because of the social crisis that paralyzes the territory.

This satellite, Eutelsat 172B, blocked in an Antonov An-124, was not scheduled for Ariane 5’s postponed launch on 21 March but for another scheduled launch on 25 April.
“Leaving this satellite in a container in his Antonov is not ideal, but there is air conditioning in the Antonov and there is no risk of degradation” the Deputy Director General of the Center National Space Studies (CNES), Joël Barre said during a press conference.

A major crisis began in Guyana on Thursday. 37 unions gathered in the Union of Guianese Workers (UTG) voted Saturday almost unanimously the “unlimited general strike” for Monday.
