Gisele -- Hottest Pilot Ever

In case of a water landing, your seat backs aren't the only thing that can be used as a flotation device.

Sources tell TMZ Gisele Bundchen is in the process of getting her helicopter pilot's license. We're told she's been taking lessons at the Marshfield Airport in Marshfield, Mass. for a couple of weeks now.

In order to complete her license, she'll need to complete 65 hours of flight time (at about $225/hr).

The friendly skies are about to get a lot friendlier.

BTW -- Gisele was spotted out this weekend looking very babybumptastic. Is flying good for the fetus?
