“This shouldn't be allowed to happen,” the Swedish Accident Investigation Board wrote.
According to the Board’s report, the pilot of the jet dipped in altitude despite instructions to the opposite.
The investigation revealed that this type of near-crash is not uncommon when it comes to military planes.
During the last nine years, 781 similar incidents have occurred in Sweden, though none as serious as the 2007 hairline miss.
“We can’t afford this many mistakes,” Göran Rosvall of the Accident Board told news agency TT. “They have to be minimized.”
