Powell as a source for Pynchon?

Anthony powell's volume 9'The Military Philosophers contains some of the best writing I've ever come across describing London during the war blitz. He captures not just the British insouciance, which others have done, but the constant fear that over times withers to indifference and uninterest - during air raids sleepers simply turn so their back is to the window protection from flying glass. We see the houses with facades standing and the ghostly interiors we walls blown away. Most powerful are the scenes of air wardens at work -!others have written of this notably Eliot but none so well - in a particularly great scene his narrator nick is assigned to watch the roofnofnhisnbuilding and given a garden hoe to break up flaming debris. The nature of the raids changed toward the end w v1 missiles no longer fleets of planes . These missiles can come at all hours so the warnings scream through the night. Nick has an awesome descriptions of three missiles slowly approaching stuttering exploding and landing out of sight. Nick and another warden coolly try to determine which neighborhood while admiring the beauty of the Thames.  It's impossible not to think of Pynchon and wonder if this novel was a source and influence - including the parallel story of the beautiful young woman having affairs w many of the officers - - as if her sexual energy is a life force and death force drawing the missiles to their targets - as in gravity's rainbow.
