While en route to a G20 summit in Buenos Aires in November 2018, the A340-300 "Konrad Adenauer" carrying German Chancellor Angela Merkel and Finance Minister Olaf Scholz had to make an unexpected landing at the Cologne/Bonn Airport. Merkel showed up late to the conference in the Argentinian capital.

It was the second consecutive month in which the "Konrad Adenauer" needed to be grounded. The A340 also left Scholz stranded in Indonesia following a meeting of the International Monetary Fund in October 2018 after rodents gnawed through electric cables.

The "Konrad Adenauer" isn't the only Airbus belonging to the German government that has experienced problems. The A340 "Theodor Heuss" jet carrying German President Frank-Walter Steinmeier experienced technical problems during his trip to several countries in Africa.

Steinmeier also had his fair share of woes with the "Konrad Adenauer" jet. The German president's trip to Belarus in June 2018 was delayed due to problems with the plane's hydraulic system.

German Development Minister Gerd Müller's schedule was thrown into chaos when he was forced to cancel a visit to Namibia in January 2018 — because of plane trouble. Müller was scheduled to depart Malawi when his Bombardier Global 5000 was unable to take off due to a defective pressure valve. He was eventually able to continue on to Zambia on a commercial flight.

German President Frank-Walter Steinmeier was grounded in Ethiopia yet again when the "Theodore Heuss" was unable to embark on its return flight due to an air pressure problem. The delay would seem to put Steinmeier ahead of Olaf Scholz for the title of German official most often stranded due to technical problems.

On February 28, 2019, Foreign Minister Heiko Maas was forced to stay overnight in the capital of Mali, Bamako, after his government plane had a mechanical problem. Maas strugged off the delay, saying he had traveled all over the world without a problem.

On April 1, 2019, the "Konrad Adenauer" hit back after a four-month overhaul. The ageing Airbus behaved badly on its first outing after its forced hiatus. Foreign Minister Heiko Maas was on board when one of the tire's burst upon landing in New York. The plane had to be towed to a parking space, with the delay forcing Maas to miss an appointment at the UN Security Council.

Also in April 2019, a Bombardier Global 5000 was severely damaged in an emergency landing after problems during a test flight. Pilots lost control of the plane shortly after take off and when attempting to land, where it jolted off the runway. The flight was a test flight after weeks of maintenance on the aircraft.

In May, Foreign Minister Heiko Maas was delayed for a third time after engine trouble struck the Bundeswehr A321 he was travelling on for his first trip to Bulgaria. The plane's pilot blamed the failure of an auxiliary turbine, which supplies compressed air to the plane's engines, for the tardiness.

A Germanwings Airbus A320 crashed into the French Alps on March 24, 2015 during a flight from Barcelona to Dusseldorf. All 144 passengers and six crew members were killed. A co-pilot with mental problems intentionally crashed the plane.

Rebels in eastern Ukraine were accused of shooting down Malaysia Airlines flight MH17 on July 17, 2014 during a flight from Amsterdam to Kuala Lumpur. All 298 people on board died, 193 of them Dutch. A Dutch investigation found pro-Russian rebels shot the plane down with a Buk surface-to-air missile launched from separatist territory in eastern Ukraine.

A Polish air force plane carrying President Lech Kaczynski crashed near the Russian airport of Smolensk on April 10, 2010. A Russian and Polish investigation found pilot error during landing in thick fog caused the crash that killed more than 90 people. Jaroslaw Kaczynski (pictured), the twin brother of Lech and leader of the ruling PiS, has suggested the crash was a political assassination.

An Air France flight from Rio de Janeiro to Paris crashed in the Atlantic on June 1, 2009, killing all 228 people on board. It took nearly two years for the black box (pictured) to be recovered from the bottom of the ocean. The investigation found a combination of technical and pilot error caused the crash.

A Spanair MD-82 plane crashed after take-off from Madrid airport on August 20, 2008, killing 154 people. Amazingly, 18 people survived the crash and subsequent fire. The crash was caused by an improper flap and slat configuration and a failure of the pilots to follow a pre-flight checklist.

A Russian passenger plane operated by Pulkovo Aviation Enterprise crashed near the eastern Ukraine city of Donetsk on August 22, 2006, killing all 170 people aboard. The plane was flying from St. Petersburg to the Black Sea resort of Anapa.

A Helios Airways flight from Cyprus crashed on August 14, 2005 near its destination Athens, killing all 121 on board. The crash was caused by a loss of cabin pressurization that immobilized the crew. The plane flew on autopilot until it ran out of fuel and crashed.

On the night of July 1, 2002, a DHL cargo plane flying near the southern German town of Überlingen struck a Russian passenger jet carrying mostly schoolchildren to Barcelona, Spain. The two men aboard the DHL plane and all 69 passengers and crew on Bashkirian Airlines Flight 2937 perished. Swiss air traffic control firm Skyguide was found to be at fault for the tragedy.

On October 8, 2001 a Scandinavian Airlines MD-87 airliner collided with a small Cessna on take-off from Milan's Linate Airport. All 114 people on the SAS and Cessna aircraft were killed, as were four people on the ground. The accident happened in thick fog. The SAS plane crashed into a hangar.

On July 25, 2000 an Air France Concorde flight from Paris to New York crashed two minutes after take-off, killing 109 people on board and four people on the ground. The crash was caused by the Concorde running over a piece of debris on the runway, which sent tire debris into part of the fuel tank that burst into flames.
