It's also enough that doing it will affect movement in a 15-20 minute
combat turn. If it's safe and reliable for routine use by commercial
traffic for take-off and landings, it's very definitely safe for combat.

The presence of such overdriving is inconsistent with most, possibly
all, of Traveller's various combat rule sets. Thus I don't have it in my
games. I use contra-grav IMTU.
