Intriguing pictures of the crash sequence on that Swiss website... It definitely was a Tiger in the colours of the Patrouille Suisse, reported to be J-3089 on Scramble news. But, given the fire seen in the pictures of the aircraft in the air, it is remarkable to see in the post-crash picture of the Swiss Ministry of Defence that the aircraft was not completely destroyed. That says something about the power of snow...
When I posted the link in the morning
there wasn't a "flaming jet pic" to be seen, let alone close-up photos of the accident scene...
It all got added later on.
