Sir Victor Goddard travelled from 1935 to future (1939 ?)

In 1935, Air Marshal Sir Victor Goddard of the British Royal Air Force had a harrowing experience in his Hawker Hart biplane. Goddard was a Wing Commander at the time and while on a flight from Edinburgh, Scotland to his home base in Andover, England, he decided to fly over an abandoned airfield at Drem, not far from Edinburgh. The useless airfield was overgrown with foliage, the hangars were falling apart and cows grazed where planes were once parked. Goddard then continued his flight to Andover, but encountered a bizarre storm.

In the high winds of the storm's strange brown-yellow clouds, he lost control of his plane, which began to spiral toward the ground. Narrowly averting a crash, Goddard found that his plane was heading back toward Drem. As he approached the old airfield, the storm suddenly vanished and Goddard's plane was now flying in brilliant sunshine.

This time, as he flew over the Drem airfield, it looked completely different. The hangars looked like new. There were four airplanes on the ground: three were familiar biplanes, but painted in an unfamiliar yellow; the fourth was a monoplane, which the RAF had none of in 1935. The mechanics were dressed in blue overalls, which Goddard thought odd since all RAF mechanics dressed in brown overalls. Strange, too, that none of the mechanics seemed to notice him fly over. Leaving the area, he again encountered the storm, but managed to make his way back to Andover.

It wasn't until 1939 that that the RAF began to paint their planes yellow, enlisted a monoplane of the type that Goddard saw, and the mechanics uniforms were switched to blue. Had Goddard somehow flown four years into the future, then returned to his own time?
