The VTIP delivery in the F-105 was done starting at 600 KIAS and 500
AGL. With a 4-G pull-up the wings level inverted position was reached
around 20,000 feet. The bomb released at 100-110 degrees of pitch
(slightly past vertical since you had already flown past the target)
and the bomb continued upward to nearly 35,000 before apexing and
starting back down.

A Half Cuban Eight means the roll back to upright occurs at about 45
degrees nose low rather than level-flight inverted. It allows you to
regain some speed.
