decides the fight! Alas for the luftwaffe the Bf109 wings were not designed
for guns etc so were not terrifically robust, the pilots were often more
worried about the wings falling off than blacking out......

Incorrect.

Having guns or not doesn't have anything to do with the strenght of the
wings. 109s from A-E had wing weapons, again one of the K models was
designed for wing weapons. The wings were also one single structure,
which made it possible to make them very strong.

"- Are the stories true, that the 109 had weak wings and would loose
them easily?
He has never heard of a 109 loosing its wings from his experience or
others. The wings could withstand 12 g's and since most pilots could
only handle at most 9 g's there was never a problem. He was never
worried about loosing a wing in any form of combat."

"The maximum speed not to be exceeded was 750kmh. Once I was flying
above Helsinki as I received a report of Russkies in the South. There
was a big Cumulus cloud on my way there but I decided to fly right
through. I centered the controls and then something extraordinary
happened. I must have involuntarily entered into half-roll and dive. The
planes had individual handling characteristics; even though I held the
turning indicator in the middle, the plane kept going faster and faster,
I pulled the stick, yet the plane went into an ever steeper dive.
In the same time she started rotating, and I came out of the cloud with
less than one kilometer of altitude. I started pulling the stick,
nothing happened, I checked the speed, it was about 850kmh. I tried to
recover the plane but the stick was as if locked and nothing happened. I
broke into a sweat of agony: now I am going into the sea and cannot help
it. I pulled with both hands, groaning and by and by she started
recovering, she recovered more, I pulled and pulled, but the surface of
the sea approached, I thought I was going to crash. I kept pulling until
I saw that I had survived. The distance between me and the sea may have
been five meters. I pulled up and found myself on the coast of Estonia.
If I in that situation had used the vertical trim the wings would have
been broken off. A minimal trim movement has a strong effect on wings
when the speed limit has been exceded. I had 100kmh overspeed! It was
out of all limits.
The Messerschmitt's wings were fastened with two bolts. When I saw the
construction I had thought that they are strong enough but in this case
I was thinking, when are they going to break
- What about the phenomenon called "buffeting" or vibration, was there any?
No, I did not encounter it even in the 850kmh speed."

Given that 109s were routinely dived at 800-900 km/hour speeds that
certainly shows that if there was some weaknesses in the plane, wings
werent' them.
