    'Theories' seem to be focusing on wet/damp/moisture in (on?) magneto's. How the hell do these engines run in the rain? and why couldn't the magneto's be water/moisture proofed?
    Of course they had to deal with this during WWII and the last 75+ years. Any experts out there that educate me on this?

    They hit a lot of stuff coming in short of the runway. I wonder what made it veer right so abruptly? I guess that's what they're trying to figure out?

    Anyone see the film of the landing?

    I don't remember that this was a big problem. In bad weather, winter, or long down times the engines nacelles were covered with a fitted tarp. I have a sense that maintenance habits have changed over the years and during the war, the airplanes were running more with less down time and there was always 4 or 5 mechanics tending to them. Early morning was filled with the sound of engines starting and then the roar of run-ups. This wet mag thing is new to me but I'm not an experienced B-17 or B-24 driver.

    Possibly moisture condensation after shutting down the evening before, especially if humid.

    I would venture this may not be that unusual, and that they could have noticed some roughness during run-up. Also not unusual to think it will clear up when at higher power settings than what is used for run-up. Pilots sometimes will extend run-up or increase power during run-up to try to clear roughness, although this is often associated with fouled plugs.

    They hit an ILS installation and that is what threw them off centerline. Then they hit something basically immovable.

    Why are people so willing to break basic rules of aviation safety?

    The comments were that it was an ongoing incremental 100hr inspection.

    I re-read one of the reports....

    Said that the 100 hour inspection on the #4 was delayed by 160 hours.

    I'm still wondering about the recommended time between major overhaul on the Cyclone.... It was at 870 hours since. The other 3 were apparently recently overhauled.

    Allegedly.....#1,2 &3 had "zero hours" on them from a recent overhaul. #4 apparently had 870 but I'm not sure that by itself was the only problem that day. Investigators found the #3 prop to have one blade feathered....which doesn't make sense.

    The only reference I found stated that a Wright Cyclone engine TBO was 1200 hours. The estimated cost for a single engine overhaul was $40,000.

    Did they loose 1 engine or 4. If one engine its shoudl not have beena problem, no bomb load, less fuel, prob less armour the plane would have been relatively light. Lots iof B17s made it back from Germany on 3 engines.

    From what I have heard, No. 4 was dead, No. 3 was almost dead, and No. 2 was having problems. Still hearsay, I guess.

    An old line mechanic posted that every hour that a B-17 flew required 10 hours of effort on the engines. He said it was a bunch of little things that made them run right or poorly.

    These are the only guys I know that are still in the radial engine business. Looks like an interesting place to visit.
