Pull upward as much as possible without stalling, so that gravity is pushing towards the rear of the aircraft. Should be possible if we're low on weight, I think.
Also, observe our surroundings. How many other aircraft are about, of what types, in what directions?
Oh, and if someone attempts to obstruct Groo's action, Groo drops what he's doing and dedicates his turn to disemboweling and then defenstrating them. This goes for all actions Groo takes, present and future.
"A fray!"
((@Egan 1d36 is simpler because it's one dieroll, which you look up. 2d6 is two die rolls, with one lookup, on a larger and more difficult to parse table. The weights and probabilities are also obvious with a d36, because you list the number of sides by nature--the 2d6 system is less intuitive and requires explanation. Finally, with 2d6 you're limited to probabilities of 11/36, 9/36, 7/36, 5/36, 3/36, and 1/36. You can't have a three and four be equally likely, and balancing nine different skill levels is more difficult because you're mostly just shifting those six around. In contrast, with a d36, you have no limits, allowing you to have equal probabilities for every result if you want, or multiple 1/36 probabilites, or just a smoother transition from unskilled to skilled.
As for physical dice... who uses physical dice nowadays? When I ran an RTD, I just genned up a hundred d6 results and just used whichever one was last for each roll. Makes each roll a simple click and backspace.))
