Level flight is not possible with a wing suit - the very best that can be achieved is a glide ratio of about 3:1 so if you're 50 feet above the bottom of a ravine, you'll crash after travelling only 150 feet along it. There are lots of videos which appear to show level flight, but they're filmed just above a sloping mountainside.
And even if level flight *was* possible, you can't just fly alongside a helicopter and float into it, due to the enormous downdraft produced by the rotor blades.
