VEEPS
Well I obviously cannot be sure it was not a 12 but, I can say that comparing the 3-view of the 12 with the 22 just now it is clear that the distribution of the engines along the wing is more 'normal' on the 12 and I don't think I would have felt it had 6 engines. On the other hand the 22 does have the big fairings which I think is what I saw when I felt it had six engines and was also surprised at how close to the fuse the inners were.
Then there was the sound - SO unusual. Plus Tiger mate reckoned he saw a 22 recently....
Suggest we let sleeping dogs lie unless an air-trafficer or somat can come up with the answer.
