B-52H Wont drop bombs from height

Can a Dev explain this?

Took the B-52H out for a test flight, got up to 42,000ft. and tried to drop bombs (500 Lb LDGP), it just says “You cannot drop bombs because of your plane’s current attitude.”

Edit* about ~33,800 and under, you can drop*

attitude??? Do you mean Altitude? If so, why is it capped for Dumb bombs? They just fall?

attitude =/= altitude

attitude is more orientation than altitude

but idk why it would block it, that image looks like it should work

I was at a massive AOA of 0.

I thought so but just wanted to say that attitude is a completely different thing than altitude
