Blackburn Beverley

T.E. North (Illustrator).  Timothy’s Book of Aircraft.  London: Collins, 1958.

Introduced in 1957, this was the RAF's largest aircraft at the time.  It continued in service until 1967.  It was named after the British city of Beverley, and only 47 of the aircraft were built.  According to its Wikipedia entry:

"The Beverley was equipped with toilets, which were situated in the tail beyond the paratroop doors located on the floor of the tail boom. One fatality was caused by a serviceman who fell twenty feet to the ground when exiting the toilet, unaware that the paratroop doors had been opened. Modifications were made to prevent the toilet doors from being opened when the paratroop doors were open."
