Subsequent developments have shown that the event described in the article was not as insignificant as one might have thought at the time of the deletion discussion. Notably, the investigation into the crash resulted in massive criticism of the flight procedures of the German federal police, and also official criticism of an EU directive that exempts police aircraft from regulations and control mechanisms imposed by civilian aviation authorities. Moreover, it was reported in February 2017 (i.e. four years after the crash) that NATO and Switzerland started a joint research project about new technologies for low-visibility flights, and that this campaign of trials was initially triggered by the Berlin police helicopter crash of 2013.
I think there is sufficient subsequent media coverage and related development to show that the complaints about the article raised in the deletion discussion can be remedied: There was extended news coverage 1.5 years after the event when the investigation report was published, and although only mentioned in passing, the February 2017 news report about the NATO trials reveals that the Berlin crash triggered a multinational development of new technology. Unfortunately I have only found sources in German but please read the following translated quotes from reliable sources:
Der Tagesspiegel (Nov. 2014): "Significant flaws and lack of communication caused the helicopter disaster one and a half years ago. ... The procedure chosen for the snow landing did follow the routines specified by the federal police but the investigating authority regards it as 'not comprehensible and inappropriate. ... In conclusion, the BFU criticised that according to an EU regulation, the operation of police helicopters is not supervised by aviation authorities and therefore not bound to aviation laws. Already in 2006, they had recommended to the ministry of transport to create legal regulations for the operation of police helicopters that 'fulfill the special requirements of police tasks and can guarantee a level of security that is comparable to the one for the operation of civilian helicopters.'" [1]
Rundfunk Berlin-Brandenburg (Nov. 2014) "Meanwhile, the federal police have mended these shortcomings by introducing special training units for landings in snow and setting up new rules." [2]
Berliner Morgenpost/Deutsche Presse-Agentur (November 2014) "Expert battle about fatal helicopter crash: An expert survey blames the federal police for the helicopter collision at the Olympic stadium. The latter party, however, rejects this as biased."
Donaukurier (Feb. 2017): "New developments for helicopter flights under low-visibility conditions are being tested. The campaign whose participants include the US Air Force, the Swiss Army and the German Aerospace Center is called Nato DVE-M Flight Trials. ... Strong swirls of sand or snow by rotor blades or thick fog may pose a threat. Even accidents tend to happen, like the one in March 2013 during a large-scale exercise at the Berlin Olympiastadion, which actually sparked the trials campaign." [3]
Moot You don't need DRV to re-create a deleted article when the reason for deletion has been mooted by subsequent RS coverage: get the text from REFUND, update it, and put it back in mainspace. I'd do it for you if I could. Jclemens (talk) 03:43, 2 March 2017 (UTC)[reply]
I'd be happy to userfy this if you wanted to update it with those links and then move it back to mainspace. Hut 8.5 07:37, 2 March 2017 (UTC)[reply]
Thank you both for the feedback. As an admin I could easily have restored this myself but to prevent a new round of deletion discussions I thought I'd better present the new facts beforehand. De728631 (talk) 08:41, 2 March 2017 (UTC)[reply]
