BRYAN EATON/Staff Photo. An 18-year-old man was airlifted to a Boston-area hospital yesterday after losing control of his motorcycle, pictured at left, on Elmwood Street in Salisbury. Salisbury fire Captain Michael Merritt said the lone rider was wearing his helmet when he crashed around 12 p.m. yesterday. The cause of the crash is still under investigation but Merritt said it could simply be a case of the driver hitting a patch of sand or some other obstruction. Salisbury police closed the road as emergency personnel transported the victim to Anna Jaques Hospital in Newburyport before being flown, via helicopter to Boston. Merritt said the victim's injuries didn't appear life threatening. Firefighters were clear of the scene by 12:45 p.m., according to Merritt.
