1. An aircraft comprising: an aircraft fuselage containing an aircraft cabin, the aircraft fuselage having a longitudinal length between a front of the aircraft fuselage and a rear of the aircraft fuselage, the aircraft cabin having a longitudinal length between a front of the aircraft cabin and a rear of the aircraft cabin, and the aircraft cabin having a lateral width between laterally opposite first and second outboard sidewalls of the aircraft cabin;a floor surface in the aircraft cabin;a galley in the rear of the aircraft cabin;an aft pressure bulkhead at the rear of the aircraft cabin, the aft pressure bulkhead including a forward wall surface facing toward the aircraft cabin and extending laterally across the rear of the aircraft cabin between the first and second outboard sidewalls of the aircraft cabin, and the forward wall surface having a recessed cavity in the forward wall surface and above the floor surface, the cavity extending rearwardly of the forward wall surface; and,at least a portion of the galley extending into the recessed cavity in the forward wall surface. 2. The aircraft of claim 1, further comprising: a galley cart in the recessed cavity in the aft pressure bulkhead forward wall surface. 3. The aircraft of claim 1, further comprising: the galley having a pair of galley walls on laterally opposite sides of the galley with rearward portions of the pair of galley walls extending rearwardly through the aft pressure bulkhead forward wall surface and forming laterally opposite sides of the recessed cavity in the aft pressure bulkhead forward wall surface. 4. The aircraft of claim 1, further comprising: the aft pressure bulkhead being a rigid, pressure sealed structure with vertical beams supporting the aft pressure bulkhead forward wall surface; and,the recessed cavity extending rearwardly between a pair of the vertical beams supporting the aft pressure bulkhead forward wall surface. 5. The aircraft of claim 1, further comprising: the aft pressure bulkhead including a first vertical beam and a second vertical beam and a first horizontal beam and a second horizontal beam, the first and second vertical beams and the first and second horizontal beams being interconnected forming a rigid structural framework of the aft pressure bulkhead. 6. The aircraft of claim 5, further comprising: the interconnected first and second vertical beams and first and second horizontal beams defining a void between the first and second vertical beams and the first and second horizontal beams; and,the recessed cavity being positioned in the void. 7. The aircraft of claim 5, further comprising: the first and second vertical beams and the first and second horizontal beams being substantially orthogonal. 8. An aircraft comprising: a fuselage having a top and an opposite bottom, a left side and a laterally opposite right side;a cabin contained inside the fuselage, the cabin having a first side wall and a laterally opposite second side wall, and the cabin having a front and a longitudinally opposite rear;an aft pressure bulkhead extending across the rear of the cabin between the fuselage top and bottom and the fuselage left and right sides, the aft pressure bulkhead including a first vertical beam and a second vertical beam that extend between the fuselage top and bottom, and a first horizontal beam and a second horizontal beam that extend between the fuselage left side and right side, the first and second vertical beams and the first and second horizontal beams being interconnected forming a rigid structural framework of the aft pressure bulkhead;the interconnected first and second vertical beams and first and second horizontal beams defining a void between the first and second vertical beams and the first and second horizontal beams, the void being accessible from the cabin and being dimensioned to receive a portion of a galley inside the void. 9. The aircraft of claim 8, further comprising: the galley having a galley floor surface that extends rearwardly into the void and between the first and second vertical beams and the first and second horizontal beams. 10. The aircraft of claim 9, further comprising: the galley including a galley cart on the galley floor surface, the galley cart extending into the void between the first and second vertical beams and the first and second horizontal beams. 11. The aircraft of claim 8, further comprising: the first and second vertical beams and the first and second horizontal beams being substantially orthogonal. 12. The aircraft of claim 8, further comprising: a pressure wall being attached to a front of the structural framework forming a rigid pressure wall structure. 13. The aircraft of claim 12, further comprising: the pressure wall having a pressure wall surface that is substantially flat. 14. The aircraft of claim 12, further comprising: the pressure wall having a pressure wall surface that is continuous, substantially flat and substantially orthogonal to the first and second vertical beams and the first and second horizontal beams. 15. The aircraft of claim 8, further comprising: the galley having a cavity, the cavity having laterally opposite and vertically oriented galley walls that extend rearwardly into the void. 16. The aircraft of claim 15, further comprising: the galley walls being comprised of portions of the first and second vertical beams of the aft pressure bulkhead. 17. The aircraft of claim 8, further comprising: a cavity extending rearwardly into the aft pressure bulkhead to a back wall of the cavity. 18. A method of increasing the floor space in an aircraft cabin comprising: positioning an aft pressure bulkhead at a rear of the aircraft cabin, the aft pressure bulkhead having a front wall surface extending across the aircraft cabin and extending upwardly from a floor surface of the aircraft cabin, the bulkhead having;a recessed cavity in the wall surface, the recessed cavity extending rearwardly into the wall surface; and,positioning the floor surface into the recessed cavity. 19. The method of claim 18, further comprising: supporting the aft pressure bulkhead wall surface with vertical beams and positioning the recessed cavity between a pair of the vertical beams. 20. The method of claim 18, further comprising: extending the floor space rearwardly of the aft pressure bulkhead wall surface.
