To put it into perspective, unless you are getting airborne off the QEC or doing a STO for periodic handling currency at home base (not the hardware store) you wouldn't routinely deploy the doors and engage the lift fan; you'd take off and land conventionally like a Tornado, Typhoon or F/A-18 does day-to-day.
Quite a lot of metal to drag about the sky?
In the end we can all procrastinate as much as we like, it won't change anything, except <hehe> the amount of ££££ that gets thrown at the project.
