One Scot is known to have died in the "appalling atrocity" when Malaysia Airlines flight MH17 was brought down over Ukraine, First Minister Alex Salmond said.
He has spent 23 years with the RAF including running the search and rescue team in Lossiemouth in Scotland for three years.
Ten of the 298 people on the flight were known to be from the United Kingdom
Mr Salmond confirmed today that one of the victims was from Scotland, as he stressed an international investigation into the incident must take place "quickly and effectively"
He said: "We have learned today that one Scot is known to have died in this appalling atrocity.
"As we prepare to welcome the Commonwealth Games to Scotland, we should note that around a third of the 298 victims came from Commonwealth nations. On behalf of the Scottish Government and the people of Scotland, I extend my condolences to their family, and to the families of all of the victims who have died in this horrific event."
He added: "It is now vitally important that an international investigation into the cause of the crash proceeds swiftly and effectively, and that investigation teams are given full access to the crash site.
"The Scottish Government is in touch with the Foreign and Commonwealth Office to ensure that any and all relevant expertise and experience in Scotland will be made available to the investigation now and in the coming weeks."
The news comes as the last two of the 10 UK victims who died aboard flight MH17 have been named in a Malaysia Airlines passenger list as John Allen and Andrew Hoare.
Malaysia Airlines has identified the nationalities of 298 people who were on board the doomed flight which includes 10 people from the UK, one of whom has dual UK and South African citizenship.
There are also 193 victims from the Netherlands, 43 from Malaysia including 15 crew and two infants and another 27 from Australia. The dead also include 12 people from Indonesia including one infant, four people from Germany, four people from Belgium, three from the Philippines plus a Canadian and a New Zealander.
Around 30 officials, the majority from the Organisation for Security and Co-operation in Europe, arrived at the crash site yesterday, about 25 miles from the Russian border, and were allowed a cursory inspection while guarded by pro-Russia rebels.
The United Nations Security Council has also approved a statement calling for a ''full, thorough and independent international investigation''.
Prime Minister David Cameron has described the catastrophe as an ''absolutely appalling, shocking, horrific incident'' that ''cannot be allowed to stand''.
A No 10 spokeswoman said: ''While it is too early to be categoric about the cause of the disaster, the growing weight of evidence suggests that MH17 was shot down by a surface-to-air missile and that this was fired from near Torez, in territory controlled by the separatists."
