In May there was another flight where a large number of passengers suddenly became ill.

Condor airline Flight DE2315 was en route from Mauritius to Frankfurt at the time it became clear that many pilots on board were suffering from a bug.

The plane landed in the German city around 5:33 p.m., where it was greeted by a large contingent of emergency services.

The crew had called ahead to alert officials on the scene of the developing emergency.

It was found that 70 of the 290 passengers on board had suddenly reported symptoms, including nausea and vomiting.

A spokesperson for the German airline confirmed the incident to the country’s Bild tabloid, adding that the crew had not been affected by the disease.

‘She [the pilot/crew] is also educated and trained for these types of special situations,” the statement to the newspaper said.

‘After careful examination of the overall situation, the flight continued. The plane landed safely in Frankfurt, where medical professionals were available to care for the affected guests.”

However, the airline did not confirm the cause of the sudden illness, but noted that the food on board was said to have been prepared in Mauritius.

‘[We have] has already launched an investigation into the matter to determine the cause and deduce possible measures from this,” the spokeswoman said.

‘Condor works closely with all responsible partners and authorities. There are currently no results available.’
