I did not realise that 23L functioned so long.
23L ? April 1974, on the final leg of my check flight to be promoted to Captain, Bahrain to London, I was cleared for a visual approach to runway 05R ! This was not a plot organised by the Training Captain, he was as surprised as I was. Visual Approach in a 707 ? Rwy. 05 R ? Never ever landed on that runway, or anything other than the 10/28's but at least it was daylight. All happened, and as I applied the brakes and shut down, the Training Captain extended his hand and said " Congratulations, CAPTAIN XXXX " Success.
