By 1977, technology had developed to the extent that Dr. Paul MacCready successfully flew a 1.6 mile-long figure of eight in his Gossamer
Condor. With the subsequent incorporation of lightweight wonder materials such as carbon fibre and Kevlar, two years later the newly
developed Gossamer Albatross achieved what was hitherto thought impossible, and crossed 22 miles of the English Channel at an average
height of just five feet!
After more successes in the mid-80s, an American craft, Daedelus, named after Icarus's dad and piloted by a Greek cycling champ, flew more
than 70 miles over the Mediterranean Sea in just under four hours, earning their creators the records for both the furthest distance flown and
the longest flight duration, despite the fact that a headwind caused the plane to ditch in the sea just yards away from our intended landing
point.

dickinson punctuation and lines in her poems to establish a rhythm. each reader will naturally find themselves reading the poem in the same way. she uses the repeating question marks and exclamation points to convey the passion in her words. shelley uses punctuation to paint a picture in the reader's mind. for example, the ellipses after "stand in the dessert" evoke a silence, as it would feel in a deserted, old place.
