I hope to get both the Sport Pilot and Private Glider certificates.

Which order would be best to get them in - would Sport Pilot be better to
get first or last?

I am especially interested in a motorglider called the Virus (what an
unfortunate choice of name!). Does a glider certificate let you fly a
motor glider?
