I'm afraid that it was (software).
Consider this:  If just ONE unprotected overflow occurs,
the mission is lost.
Not a SINGLE unprotected conversion should have been included.

The fact remains that in that real-time system,
unprotected conversions were included.

No-one experienced in real-time programming
would have permitted those unprotected conversions.
