Hi folks

Look at this big seaplane, in the photograph of Professor Edmund Rumpler with one of these big projects, the Riesenflugboote of 1925.

The second illustration is another german project, the Schiefer Flying Boat of 1926.

Third is the LFG V3A of 1921

The last ones you can find it in http://www.msacomputer.com/FlyingBoats-old/

if somebody has more information, please tell us!

Saludos

Fabián

The P 200 images are derived from this. Some of the images in Pohlmann's book are lifted straight from the original documents but others, sadly, are inaccurate redrawings. I suppose that when he wrote it he was just shooting for an overview - IIRC it's a sort of vague autobiography, rather like the one written by Vogt.

Pohlmann's book is an attempt at a history of the whole Hamburger Flugzeugbau enterprise, from its foundation as an offshoot of B&V to its reintegration during WWII to its reformation afterwards. There is relatively little autobiography; Pohlmann himself only joined when Vogt was snowed under as WWII got into its stride. Indeed, Pohlmann returned when the remaining Blohm resurrected the company, yet tells nothing of his time there.

You may be mixing his account up with Hans Amtmann's memoir on The Vanishing Paperclips. Amtmann was head of Preliminary Design under Vogt and also led some of the big flying-boat projects, especially the P 200, due to his prior experience.

The Rumpler looks like it had potential. There must have been some large floorspace in it. But what happens when the guests all rush to one side and there is no FCS to compensate? People do stupid behaviors when in a mob.
