Hi Marco
I have some loose notes about this interesting pilot..
He actually was a pre-war pilot with certificate nr 245 dated 26 Jun 1912.
I dont knew where he was when the War started but in mid Febr 1915 he was at proceeder of the LFA at Johannisthal. I do belive that he was a pupil there for becoming a military pilot too, so I dont think he was an instructor. He hold the low rank Mtr(Matrose) there. One of his observer there was another Mtr Dr. Moritz Wirths who he served later together with.
Later in spring of 1915, Hasenkamp was serving within the LFS(Landflugstation) in Wilhelmhaven now with the rank Bts.Mt. And on 14 April 1915 he replaced Schmidt as pilot within Landfliegerabteilung I stationed at Mariakerke at the front.
During his serving in LFA I he was promoted to Ob.Bts.Mt on 20 Jun 1915. He had earlier received the Landfligerabzeichen on 12 May 1915.
With the formation of Landfliegerbateilung III on 20 Jul 1915 he was one of the pilots who went over to this unit. He flew AGO 77 there together with Fähn.z.S Leberecht Gebhard von Blücher. Sometimes in Aug 1915 he however returned the LFS in Wilhemshaven.
On 5 Sep 1915 he was posted to the baltic(Kurland) for serving within FFA 37, an Army unit. Within this unit he met Dr Wirths again and another observer joined about two months later. Oblt dL Vogt(sometimes spelled Voigt) who also had served within LFA III.
Do anyone has Vogts first name..??
With the creation of Marine Air ranks he become Fl.Ob.Mt(Fluobermaat) in Nov 1915 and on the 23 Nov 1915 he was decorated with EKI...!
However he had the "bad luck" to be promoted to Fmst(Flugmeister) on 20 Dec 1915, which meant that it was nearly impossible to become an officer,
About there stops my further information. But his possible "old" friend Vogt had become commander of the HSS(Hallenschutzstation) in Tondern in spring 1916...Therefore I believe that it is possible that also Hasenkamp joined this unit and not the Zeppelin part...?
But I havent read the KTB of this unit yet..
