No, Bumper-Wac was not the first rocket into space. No more than Alan Shepard was the first Man into Space (there was this guy named Gagarin who not only mde it into space for 5 minutes, but actally orbited, a month before).
I do not know why the achievements by VonBraun and other members of his team keep getting underplayed over time. I wonder if the Wright Brothers grew up in Germany and achieved what they did, would they now be recognized for the first heavier than air airplane flight, or would there be nit-picking over data?
There is this, about 1/2 way thru the page, from:
https://www.v2rocket.com/start/makeup/design.html
The A-4/V-2 rocket had an operational range of 234 miles. The max. burning time of the engine was 65-70 seconds, shortly before engine shutdown the A-4/V-2 weighed 4040 kg at a height of 35 km, starting with 1 G force, and at shutdown 8 G, after shutdown the rocket flew to a height of 97 km and fell to earth with a impact speed of 3240-3600 km per hour.
So, even when flown angled, as a missile, it reached about 97 km, just 3 km shy of the magic 100 km threshold of space. So is it so hard to believe that any V-2s set to fly vertically could not easily bust 100 km? Just because there may not have been proof to show that some certain flight flew to exactly say, 187.23 km high, does not mean one should then ignore the prospects that it DID fly into space. Since all it had to do was fly to 100 km, which was just a few km more than it often did when flown at an angle (maybe around 45 degrees or so) for horizontal range.
Actually, when flown against some targets that were closer than normal range, it may have flown a slightly steeper trajectory, so it may have exceeded 100 km altitude. I just do not know enough about how the V-2 guidance handled range to know whether they adjusted range by trajectory angle, or loaded it with less fuel, or fueled it the same very time but had the engine shut down early.
But even if that does not do it, that nothing that flew in Germany is valid, only what flew in the U.S., then there is this quote from the following page about White Sands tests:
https://www.designation-systems.net/dusrm/app4/v-2.html
One launch in December 1946, which had reached an altitude of 187 km (116 miles), achieved the absolute altitude record for single-stage rockets until it was surpassed by a RTV-N-12 Viking on 7 August 1951.
So, I am somewhat baffled why this Bumper-Wac is being bogusly promoted as the first rocket into space. It was not. It was probably the first rocket not built ENTIRELY in Germany to go into Space due to the US-built Wac upper stage that was added. And perhaps that is the clue right there. Not history, not science, but politics. So maybe I am not far off, maybe by 2011 the 50th anniversary of Shepards flight will be promoted as the First Man in Space (Cant believe those Russians....).
Notable things about Bumper-Wac were these: First successful 2-stage rocket. A flight that significantly raised the Space Altitude record. And, a later Bumper-Wac happened to be the first rocket to be flown from a desolate crude swampy site near the Atlantic Ocean, named Cape Canaveral.
