Concorde crash was FOD damage, a piece of debris damaged the landing gear which ruptured the wing of that plane, causing a fire which melted the wing until the plane crash.
Meanwhile in the case of PIA8303 the captain came in too fast didn’t put out the landing gear(wheels) landed on the engine pods, took off again but because the engines were damaged by the earlier landing attempt the plane stalled and crashed into the neighborhood.
In the PIA crash there was no external factor contributing to the crash, only bad decisions by the pilot.
The Concorde crash was caused by the poor and fragile design of the aircraft.
