To ask the Secretary of State for Defence, pursuant to the oral contribution of the Minister for the Armed Forces of 15 January 2018, Official Report, column 605, how many former pilots who had left the RAF have applied to re-join since the announcement that his Department would purchase nine P-8A Poseidon Maritime Patrol Aircraft in July 2016.

At 17 January 2018, 38 former RAF pilots have applied to re-join the RAF since July 2016<<
Presumably these are Nimrod fugitives as opposed to airline fugitives with B737 experience?
