In 1963 the Senior family survived the Lakonia disaster, on the evening of 22 December, the Greek cruise liner TSMS Lakonia (formerly the Johan Van Oldenbarnevelt ‘JVO’) caught fire and was abandoned[2] in mid Atlantic (later sinking under tow to Gibraltar), of the 1022 souls on board, 95 passengers and 33 crew members lost their lives, many due to the swamping of the ship's life boats.

At the subsequent Board of Inquiry the Lakonia's seaworthiness and the behaviour of the Captain and crew were severely criticised, leading to criminal charges being brought.

As a result of the disaster a thorough review of maritime safety law was undertaken leading to significant changes in the rules allowing ships to sail from port, if deemed unfit for sea.

Senior was caught and arrested holding down a barbed wire fence whilst in a state of undress, his compatriots successfully escaped but were later identified when they reported to the Matron's office requiring first aid to lacerations of their abdomen and upper thigh areas.

In Jan 2016 Her Majesty the Queen appointed Senior a Member of the Most Excellent Order of the British Empire MBE for services to the British Armed Forces and the Borough of Scarborough and later the same year, the Vice Chancellor of the University of Hull Professor Calie Pistorius conferred Senior with the honour of becoming a Doctor of the University (Honoris Causa).
