I guess the barrier must have been at the end of the runaway separating it from the beach. The Indian Navy lost two Illushin marimatime recce planes in an accident last year at GOI as well. This accident must've thrown schedules all over the place, but not as bad as the MiG crash at Bangalore.
I believe that the armed forces and civilians should not share facilities - Daoblim is too cramped to deal with both the tourist influx and the Navy's needs. Goa needs an airport dedicated for civilian air traffic.
