The intervalometer had a minimum 1/20 second sequence. The circuits closed in order so the bombs above wouldn't fall before the ones below were released. (Usually)
Even that minimum gives around 44 yards separation on a plane travelling at 180MPH. or 1/8 of a mile for a stick of 5 bombs.

Keep in mind the indicated air speed on the B-17 during the bomb run was 150 mph. The actual ground speed could be more or less depending on the wind and crab. the trajectory of the falling bomb varied with each type of bomb. The intervelometer settings included settings for train release and ground speed. The height of the target above sea level also effects the bomb trajectory because of the lower densities encountered. So many factors affected the actual bomb impact distance on the ground.

Thanks Bill but I was cheating, 180MPH may or may not be close to the bombing ground speed, it is exactly 3 miles minute though.
 
The point I was making was that looking at a picture of the bombs leaving the aircraft it is hard to imagine they would land so far apart, all based on identiacal ballistics of course which is impossible.
It has to do with the issue of distance covered versus time: If you're doing 150 mph, you're covering 220 feet per second, so if one bomb comes off a second after, even if it's ballistic arc was exactly the same, it left the plane one second after, so will land 220 feet further downrange.

Admittedly 150 mph indicated airspeed at 25000 feet is something like 230 mph, so it'd be more like 337 feet: If the intervalometer was set for 1/20th a second release it'd be a little under 17 feet between each bomb.

Zipper may well still be a wee bit younger than most of us.
I'll be 34 in 13 days...
I'm 67 and still get miffed at kids not knowing who Jimmy Doolittle, Douglas Bader, Francis Gabreski, Gregory "Pappy" Boyington or so many of my other childhood heroes are or were.
I'm surprised they wouldn't know who Doolittle was, I know who Gabreski and Boyington are... I'm not exactly proud of not knowing who Douglas Bader is -- though after doing some googling -- I know he was a WWII ace who was shot down in 1941 and was held at Colditz castle until the wars end.

I did know of an ace who lost his legs and flew with prosthetic and could hold higher g-loads ironically because of it: I did not know it was him (I usually tend to remember things like that)
 
Bader lost both legs just before the war due to performing low level aerobatics in what if I remember the book correctly, was a Bristol Bulldog. The only other amputee that I know of would have Hans Ulrich Rudel having lost one leg in combat and still continued to fly JU-87s into combat.
 
Bader had a movie made about his life during the war, Reach for the Sky. It was on every boxing day when I was very young.
 
I never knew about the movie. I read the book a number of times as child. I have a copy of "God is My Copilot" that I still read sometimes.
That is why I'm enjoying Bill's snippets of information so much. Thank you Bill for the first hand accounts.
Bader had both legs amputated one above and the other below the knee. The movie was filmed in a deep rose tint, ignoring many of the controversies that surrounded Bader.
 
Aviations version of beer goggles?
I remember watching it as a starry eyed kid thinking everything on TV must be true. My father just remarked that "there were many people hated his guts" which confused me a lot. To me he was a man of his time, he isn't here to defend himself and there is no rule that says heroes have to be perfect in every way at all times.
 
Thanks kindly, you saved me a ton of reading. If I post something I have to find the source and this would have consumed me
Do you think I am an encyclopedia? Google is your friend, I just googled "RAF pilot amputee" and it is the third result.
 
Sadly the internet in camp is sketchy at best, think dial-up but 10x worse. If a thread here or on another site has photos....forget it. I get booted from this site 3-5 time in half an hour and this is my 3rd attempt at writing this post. When I get home after a week in camp I have a minimum of 7 pages to catch up on from this site. Thanks again for the link, I'll read it when I get home
