Was the Norden bombsight really that crap? (3 Viewers)

OK, we just have a different definition of precision. I was thinking of a single ship or particular building. Railyards and oil facilities I would have described as small areas.

Area target - target an area of a city.
Precision target - target specific facility, building or complex.

For both the RAF and Eight AF heavy bombers flying at altitude, aiming at a single building ends up with damage to an area (hopefully) around the target.

If the aim is to only hit a single building, attck during the day with Mosquitoes, or similar aircraft, and use visual aiming.

Hitting manoeuvring ships at sea is a more difficult proposition.

Here's a question re: Norden some of you may know the answer to:

I was watching "Masters of the Air" on AppleTV last year and there is at least one scene where aircrew take time to destroy the Norden before bailing out of a stricken aircraft.

I'm assuming that at least at some point in the war this was an actual standing direction to aircrew. And I couldn't help but wonder if/how many airmen were killed while trying to dispose of the "top secret" bombsight when they could have egressed their planes.

Because there's a particular tragedy to the idea of a man going down with his plane to preserve a state secret that A) isn't a secret and B) is of minimal value anyway.

I know that USAAF figured out pretty quickly that real world accuracy from high altitude was fairly low, even with the Norden, but I'm wondering to what extent they (i.e. intelligence and brass) actually believed as the war went on that Norden represented a genuinely significant qualitative edge over comparable enemy equipment. The kind of technological secret you'd want your trained men to risk their lives to protect.

Also to what extent this sort of policy would have been partly a question of keeping up morale: "We've got this high-tech superweapon the enemy doesn't know about!"

I'm sure I'll read more about it as time goes on, but I figured based on the depth and breadth of knowledge so many folks here have, you might be able to fill in those blanks a bit.

Thanks!

Hitting manoeuvring ships at sea is a more difficult proposition.

A lot more challenging with no way to anticipate the motion of the target after bomb release. One solution was a low level attack allowing the minimum time for ship travel. The Mk III bombsight could be used for 50' to around 600'. (Sometimes claims of up to 1,000' are made). The Mk XIV was used at 1,000/1,200' particularly by Coastal Halifaxes. The other option was the LAB when the ship might not even be aware of a pending attack until the bombs exploded. There would be no need to approach at speed so they were hard to hear.
