Paninternational Flight 112
The aircraft involved was a BAC One-Eleven registered as D-ALAR and first flew one year before the accident.[2] After the takeoff, as the aircraft climbed through 300 metres (980 ft), both engines failed and the captain decided to make an emergency landing on a highway – Bundesautobahn 7 (also part of European route E45)[3] – about 4.5 km (2.8 mi; 2.4 nmi) from Hamburg Airport.[1] During the landing, on the south-bound carriageway to avoid heavy traffic out of Hamburg, the aircraft deflected to the left and collided with an overpass and multiple concrete pillars, causing the right wing, cockpit, and T-tail to shear off.[1] Subsequent investigation showed that one or two of the five tanks for the water-injection engine thrust-augmentation system (used during take-off) had inadvertently been filled with kerosene instead of with demineralised water.[1][2] Spraying this additional jet fuel into the engines caused them to overheat and fail shortly after take-off.
