Not sure if any of these images were posted before - I just found them, when I went through
the latest photo additions in the B/W archive of the "Wingnut Wings" website.
They do not only make great WW1 aircraft models - the archive is top notch, and it's getting
updated quite frequently.

Hansa-Brandenburg attacking Felixstowe seaplane

Nice, I'd never seen that before.

Wow, those were some very cool photos indeed, thanks for the head ups , Olham!

Here's another view:

The crew was dead after the attack, I guess...

Not necessarily, no. In one picture you can see a crew member on the outer right wing.
But the aircraft was most certainly lost. I hope they had rubber boats.

Thanks for the new pic, Jim!
