I know. Back when Boeing was still based.
Funny enough the “upper stage/upper plane” has 6 km/s of delta V even with 400+ tons of payload. A lunar transfer is 3.2 km/s, orbit insertion is 0.9 km/s, and landing is 1.7 km/s. TLDR; a fully fueled upper stage in LEO could land 400+ tons on the moon, despite being a fuckhuge spaceplane.
