On 15 November 1942 the G-AGBB Ibis was attacked by a single Messerschmitt Bf 110 fighter, but was able to limp on to Lisbon where repairs were carried out.
Although there were still two other KLM DC-3's and one KLM DC-2 in use by BOAC on the same route only the G-AGBB Ibis was attacked three times.
