Hang Glider

Imagine this scene: You and your mates are fighting off a zombie tank, in an attempt to defend your favorite hot dog place, The Black N' Yellow, when suddenly some guy, in an attempt to get your attention, accidentally beans the biplane you're riding in with a flare, sending it spiralling to the ground and right into the hands of the big bruiser.

Most people would be royally fucked at this point, but luckily, you brought along your trusty hang glider!

With it in hand, you quickly dismount the burning wreck and make a break for it, using the thermal lift generated by the flames to boost yourself into the air and glide away from the action, ducking into a nearby house.

The Hang Glider is the ultimate 'get out of ass kicking free' card. With it's ground breaking 'unpowered' technology, you can easily jump out of the fray and simply glide away to fight another day. However, please note that since the glider is unpowered, you have to build momentum somehow, like getting a running start or starting at a high place and nose-diving until you reach the point where you're generating contrail.

Or, you can rocket jump!

I rather like that option.
