I remember when I was a child, my parents and me often saw the Aunt Ju flying. But about 5 years later it disappeared. We never saw it again.
Does anybody know what has been the use of the Ju 52 after the 70s?
At least for Germany I can assure it still flies!
I live in Germany near Frankfurt and Egelsbach. Frankfurt is probably known, Egelsbach is 20 km south and has a quite large "airport" for private aviation (I don't know the proper term. There are no scheduled flights.)
During summer Aunt Ju can be seen (and heard!) here every few weeks. You can book sightseeing flights (e.g. here or here) or one-way flights. The two Ju52's usually seen here are the "D-AQUI" and the "HB-HOY". They tour throughout Germany until autumn and are then revised until next spring.
An excerpt of the next year's schedule for the HB-HOY shows three sightseeing flights around Egelsbach and Frankfurt, 40 minutes for ~280 EUR (~330 USD) and a one-way flight to Essen (60 mins for 250 EUR).
During the last years the D-AQUI also
hopped flew from Egelsbach to Frankfurt (that's just 10 minutes). They say the next year's flight plan for the D-AQUI will be released in January 2018.
I'm sorry that most of the links are in German.
Sadly, just yesterday (Aug 4 2018) one of the Aunts, HB-HOT, crashed in Switzerland. All twenty people aboard died. They don't know the reason yet.
Again, sad news: The Lufthansa (which sponsors the "D-AQUI") has decided to stop their sponsorship for the maintenance. They say it's just too expensive for them to keep their Aunt Ju airborne for passenger flights. So "D-AQUI" will not be seen or heard any longer regularly. Unfortunately I have only German reference for this on www.spiegel.de (a major German news magazine).
According to Wikipedia there are still 8 JU-52's flying today. Which one do you remember seeing flying?
The JU-52 trimotor is approaching 90 years old. In its time it was a slightly larger version of the Ford Trimotor. Corrosion and age are grounding the remaining airframes (Central Europe is no Arizona). The corrugated skin worked very well to improve skin strength. The cruise speed of around 100 knots did not present excessive drag penalties. The JU-52 carried a crew of 2 and around 17 passengers. It's innovative "double wing" slotted trailing edge gave good low speed performance, much like Fowler flaps today.
This type generated some interest when Siemens came out with their electric aircraft motors, with the possibility of mounting the electric in the nose for takeoff performance and using the gas motors to maintain charge. Maybe they will build some new ones this century.
