I am afraid of heights! Can I still do it?

Believe it or not, but many pilots (paraglider, hangglider, fixed wing, etc.) are actually afraid of heights. There is a significant difference between standing on the ground on a high, exposed place like a tower or a bridge, and being completely disconnected from that ground, flying in an aircraft of some kind. So give it a try; if you are uncomfortable, your instructor will get you safely back to the ground straight away.
