A digital zoom lens?

Yesterday I was on the beach in Wijk aan Zee, where I happened to see paragliders in action.

I also spoke with some paragliders. Nice guys, talkative and happy to be active on a first sunny west wind spring day).  They made me enthusiastic about their sport and it was a joy to photograph them. I briefly wished I could lift off -so seeming smoothly- and glide in the air too… But soon I had another wish : a zoom lens on my dslr. I could not quite capture them in the air as I wanted. I guess a zoom lens would have suited me better.  Now I am seriously rethinking a 24-105 again. Or will my dream lens be launched shortly : light, small (digital zoom lenses are so big and heavy!), sharp, all purpose and crisis affordable. I wish / eye wish…
