Helicopters in service
A helicopter does not need a prearranged landing site but can land anywhere on a sufficiently large surface.
It can also be equipped with a winch, which means that it does not even need to land, but can rescue those in distress in water, boats or other inaccessible places from a hovering position.
The Air Force acquired 10 Boeing Vertol 107s which were assigned the designation Hkp 4A with first delivery in 1963. The helicopter was based on F 8 Barkarby which became the mother flotilla, and later also on F 15 Söderhamn, F 17 Ronneby and F 21 Luleå which formed permanent air rescue stations.
Detachments were established by F 8 at Berga, outside Stockholm, and in Visby in 1967. When F 8 was decommissioned (1974), these helicopters were transferred to F 17, which took over responsibility for Berga and Visby.
The last flight with Hkp 4 was carried out in January 1992 from
F 17 via Visby to Barkaby for storage and decommissioning.
The Air Force flew Hkp 4 more than 62,000 hours without a breakdown or
more serious incidents.
