Saving your airline money
Get a winch launch to 3000' and then fire up the engines when airborne.
Take off at E.mids and land at Birmingham. Convince your passengers it is their destination (Bahrain) bluffing that we had one hell of a tail wind.
Serve 'Peckham Spring' water instead of Evian.
Fly inverted so all the change falls out of the pax's pockets. Present your haul the CEO of the airline.
Turn off the heating and let the passengers freeze. Then offer to sell them overpriced ski jackets and thermal underwear.
Lastly, when airborne, insist the passengers have to pay an extortionate price for oxygen or you'll cut off the supply and laugh at them as they slowly turn blue.
