Jet crew averted Dublin air disaster

THE crew of a jumbo jet averted disaster in the skies over Dublin when they managed to land the aircraft without knowing how fast it was going or how high it was flying.

The Boeing 747 cargo plane operated by United Parcel Service caused a full-scale emergency at Dublin Airport when key instruments failed after a pre-flight checking error by maintenance staff.

At one point as the flight commander turned the stricken plane for home, he had three different speed readings ranging from 170 knots to 300 knots and did not know which, if any, was correct.
