Here is an update on the situation:
"SO it's official, Jade knows more about aeroplane toilets than Alex, PJ and Tim.
Jade insisted this morning that she used stairs to visit the ladies room during a flight to the Dominican Republic last year, a claim that was met with a mixture of mockery, scorn and sarcasm from PJ and Alex.
The twosome reckoned what Jade had experienced was either a dream or a bad case of altitude sickness. The argument rumbled on and even resurfaced over supper, when Tim and Alex once again put Jade down. "It's physically impossible," insisted Alex.
But the dental assistant stuck by her words adding she remembered a perfume cabinet and that the walls of the toilet were light green.
Earlier, it was Tim who sowed the seeds of doubt when Kate asked if he had heard of planes with downstairs loos. "Well, 747s have stairs upstairs in first class. She'd have to be sitting in business class to go downstairs," he reckoned, clearly suggesting he thought such a scenario was unlikely.
But it seems we should be taking Jade seriously after all, as you lot clearly know your cargo holds from your cockpits.
Lesley emailed: "The plane that Jade spoke about this morning does exist - it's a British Airways Boeing 747. We flew on this to Miami."
Anthony, took the attack on Jade so seriously he looked into it in admirable detail. "You may be interested to know that Jade is correct! She probably travelled on an Airtours Airbus A330-200. To quote the company: Airtours International has the first A330's in the world to feature downstairs toilets. Five of the seven on board are situated on a downstairs deck, accessed via a stairway at the centre of the aircraft."
I know when I'm right
The Airbus theory was backed up by Trevor who went on by way of a disclaimer to tell us, "I only know this through work, not through any anorak-related activity."
So it is great delight that, for once, we can slap our Jade on the back for sticking to her guns on this issue.
And were we able to convey a message to PJ, Alex and Tim, it would be this: How stupid are you?"
