A police inquiry into so-called rendition stopovers was ordered by then lord advocate Frank Mulholland in 2013.
Politicians welcomed the breakthrough but demanded Mulholland's successor James Wolffe "outlined where the investigation is going".
Campaigners have compared the US planes to getaway cars used in bank jobs - and say the investigation into whether they broke Scots law is vital. Scottish Greens justice spokesman John Finnie, who described rendition as a "vile practice", gave a "qualified welcome" to the news.
He said: "I plan to write to the Lord Advocate again on these important developments."
Liam Kerr, Scottish Conservative justice spokesman, said: "The previous Lord Advocate had committed to investigating this matter. The current Lord Advocate must now outline where that investigation is - and where it is going."
Dr Sam Raphael, of research group The Rendition Project, said: "Scottish territory was a vital part of these torture flights.
"The question remains: Can those involved in these serious crimes be brought to justice?"
We revealed in 2014 that police were investigating at least six stopovers - four at Prestwick airport and two at Glasgow.
Research by academics suggested 13 possible rendition flights also landed at Inverness, Wick and Aberdeen between 2004 and 2006. When Mulholland informed MSPs in June 2013 that the flights would be probed by police, he said:
"The use of torture can't be condoned. It is against international law and contrary to the common law of Scotland."The US Senate issued a partially classified 500-page report on the CIA detention and interrogation programme in December 2014. Police Scotland asked the following year to see the full 6000-page report, which would reveal dates, locations and other details removed from the 500-page version. Scottish detectives have never received it.
It would include information that nails three flights which touched down in Scotland as being involved in transporting suspects for torture. One is Khaled Sheikh Mohammed, rendered from Afghanistan to Poland for torture in 2003.
Gulfstream jet N379P - dubbed the Guantanamo Express - stopped at Glasgow Airport in March 2003 on the way back from dropping him at a CIA torture prison in Poland known as Detention Site Blue.
In evidence to the Intelligence and Security Committee, Police Scotland Chief Constable Iain Livingstone said US officials had refused permission for officers to board a flight to check the occupants. We told last year how police said they have no idea how much the five-year probe has cost taxpayers.
They said they did "not hold information" on the cost.
Police Scotland confirmed that the report had been submitted to the Crown Office.
The Crown Office said they had received the information, now being considered by their Serious and Organised Crime Division, but could not comment further as it was a live investigation.

Think of what the average AmurKant will say: "See? They're letting them pray." No, if they were praying, they'd be all facing Mecca, plus other differences about which I am unfamiliar.
Rather, it's just a form of 'static positioning' torture.* They probably had to each kneel there for hours. You try it. (Just providing 'entertainment' for AmurKant's 'Soldiers' - out there on those 'oh so dangerous front lines, which AMERIKA's Acts of War have created!

*I'm sure that there's another name for it, but it's still, simply a lesser form of torture. A more infamous picture of other, more 'creative - i.e., sadistic uses of that technique is the iconic photo of 'detainee'** called "Gilligan". He's hooded, el-gharib prisoner with wires standing on a box, with wires wrapped around his toes and fingers over a wet floor and was told that if he touched the ground, he'd be electrocuted.
For that picture and more 'fun with torture' details on that, see Torture, Rendition, and other Abuses against Captives in US Custody " at Historycommons dot org. [Link] (Full report about halfway down the page. Hit Control-F, type or paste in gilligan.

** Another bit of subtle Orwellian mere word propaganda. Americans get "arrested", and 'allegedly' did things before trial, and afterwards are 'convicts.' We treat ou Convicted death-row inmates (DRI) (Danny Rolling or William Cruz, among other Florida DRIs comes to mind) better than these poor detainees, who mostly had more land than their neighbors, or a prettier wife, and the US admits X# were tortured to death.
