I found it pretty easy on the level where you go into the bank (is that the face-off level?) Before you go into the bank, you have to pull two switches and start an elevator going up and down. Get on the elevator and when it gets to the top, don't go in, but instead, jump off with the glide suit. You'll have plenty of time gliding, PLUS, if you glide to the right you can easily get over to the hostage area without the struggle to jump up th ledge, which I found nearly impossible to do.
