Aviation authorities launched a formal investigation after a medical evacuation helicopter crashed on Mount Kilimanjaro, killing all five people on board. Simon Maigwa confirmed the victims include two Czech tourists, a Zimbabwean pilot, a local doctor, and a mountain guide who perished at an altitude of 4,700 meters. The tragedy follows a June EU flight ban on Tanzanian airlines and represents the first fatal aircraft accident in the Kilimanjaro region since 2008.Investigators are working to determine why the Kilimanjaro Aviation aircraft went down between Barafu Camp and the Kibo Summit during a rescue mission. The crash occurred on Christmas Day as the crew attempted to transport the foreign tourists for medical treatment on Africa's highest peak. This incident has raised further safety concerns following a major crash into Lake Victoria in 2022 that resulted in 19 fatalities.The Tanzania Civil Aviation Authority stated that the inquiry will follow international safety standards to uncover the cause of the deadly accident. While such crashes are infrequent in the region, the recent history of Tanzanian aviation led to international scrutiny earlier this year. No Swedish citizens were among the deceased in this latest mountain tragedy.
