Some news sources are saying it's much more serious.
A crash in the mountains in fog, with the helicopter and its occupants "missing".
Iran state media are the ones saying it was a "hard landing", but are probably desperate to downplay the incident, at least until they actually know what happened.
I have a friend who is from Iran, who was telling me earlier today that there is almost universal rejoicing among ordinary people over the death of Raisi. They are well aware of his history as a murderer who had been personally responsible for many deaths.
Meanwhile, the government has announced five days of mourning and state-run media say he was "martyred", which is difficult to square with what we know of the circumstances of his death, unless they're going to spin it to look as if there was some "interference" - foreign or otherwise.
Apparently their helicopters are all old. I doubt they have the spares to maintain them properly, even those used by the government. I wouldn’t like to be one of the maintenance engineers that signed this one off.
The helicopter that crashed was one of the newer helicopters owned by the Iranians - A Bell Ranger.
Military helicopters mostly date from before 1979 (45+ years old) when the Shah was overthrown and the Clerics took over.
Age combined with the limited availability of spares means parts for planes, helicopters, oil industry, power generation etc etc are crucifying the economy.
Now we know why the Iranian state-run media say he was "martyred".
Apparently it's all the fault of the Americans, because their sanctions mean that aviation spares are unobtainable.
A pretty stupid idea, as it's a tacit admission that the helicopter was not being properly maintained and yet the president was still allowed to ride in it.
An older helicopter flying over mountainous ground covered in fog... carrying your top leaders... a recipe for disaster, always seems an odd mode of transport to use for your heads of government/state.
Seems a clear cut case of flying into cumulus graniticus.
But it also looks like a very old single engine Bell. Even a modern helicopter with all singing all dancing kit wouldn't be my choice in 8/8 on the deck cloud.
Hence boycott of new aircraft/helicopter & a parts embargo - so far lasting 45 years
They still buy some parts via 3rd countries BUT even legitimate supplies for 45 year old helicopters are difficult to find - even for helicopters within the USA itself.
I was watching some stuff about this. Generally thoughts were he's a nobody, he has no power backers, no base. He's not from a foreign policy or security background. His job is to parrot the lines given to him. It changes little in iran as its destabilises or changes nothing. Plus there's a pretty poor air safety record in iran
