At 09.00 on Monday 3 December, after embarking a number of VIP's, Ocean weighed anchor and steamed into the Channel on what was an overcast day, into a moderate swell and 17 knot south-westerly winds. At 10.55 the ship went to flying stations and an hour later at RNAS Ford, Lt-Cdr E M Brown RN took off in a prototype Vampire jet fighter, bound for Ocean where he was to make the first pure jet carrier landing. Captain Brown describes his experience:
"In overcast conditions I found Ocean ploughing along rhythmically, and screeched over her with a low pass and roll to announce my arrival. Unknown to me at that precise moment the ships loudspeakers were announcing that the Vampire had been ordered to return to Ford because the boffins felt the flight deck was pitching excessively. However, Caspar John had been Captain of the Pretoria Castle, the trials carrier, when I was in Service Trials Unit, so he knew me well and he immediately decided to accept me for landing. The combined ships speed and wind speed over the deck was given to me by radio as 38 knots with the flight deck pitching 12 feet at the stern and rolling five degrees."
Brown's landing circuit was begun at 1000ft, at 200mph, with the Vampire's engine well throttled back. His final turn-in was a fairly wide sweep made in a nose down attitude at 115mph, losing 100ft in height so that his straight approach was begun at 300ft. Once again he takes up the story:
"Speed was reduced gradually to 100mph, until a position about 150ft aft of the round down and 30ft above the flight deck was assumed. From this position the throttle was cut and no further movement on the elevators made until the round down was crossed at 95mph, then the stick was eased back fairly sharply until the aircraft stalled completely as I felt by the kick on the port aileron as the port wing dropped. Although I aimed for the No 4 arrestor wire, the flight deck was on the upswing of its pitch as I crossed the round down and in consequence the hook picked up No1 wire and I came to a halt with astonishingly mild deceleration."
Lt-Cdr Brown had successfully accomplished the first deck landing of a jet aircraft, and the ships log recorded the event thus:
"11.27 - De H Vampire landed on".
The Vampire trials continued each day, with Brown making a number of landings and take-offs, which he decribes as follows:
"The aircraft was held on the brakes until the full 10,200rpm were reached on run-up, and the released and the stick held central until 60mph registered on the ASI when the stick was eased back until the tail booms were estimated to be one foot off the deck and I passed the island superstructure at bridge level."
During the afternoon of Thursday 6 December, with the trials having been completed, Lt-Cdr Brown took off from Ocean and flew ashore.
