Sorry to hear that. But don't despair, it's always a good time to start.
In this case, I would recommend some reading of History books on the period known as "European Medieval" (I don't know if that's the exact English term, sorry). Fascinating stuff.
The odd thing is, before the West was radically religious, it was the Muslim world which was tolerant and open.

The difference is that the WWII planes could only do it in a near-suicidal dive. The X-1 could do it intentionally, under normal powered flight.
2 things you may not know:
- The Me262 was a jet fighter/bomber. WWII plane. As cited in a post above, some claim it broke the sound barrier in levelled flight.
- The Me163 was a rocket fighter. Some claim it broke the sound barrier in 1944. The Bell X-1 is almost a copy of its design.
No official world records, I'm afraid. Well, there was this war going on, that made quite difficult for international records bodies to arrange for a convenient validation spot...
Of course, these planes were on the wrong side of History. So hardly anybody today knows they existed at all...
Too lazy for links. Just google "Me163" and "Me262".
