Mobile phones might have changed things at Arnhem. If I recall all the radios had duff frequencies, hardly able to signal from one side of the road to the other....
Glad to see both of you back, been a bit too quiet without you!!
I suppose if I suggested SatNav, I'd upset the Navigator fraternity, but what other modern invention would have proved worthwhile on the battlefield?
Infra red? Heat seeking missiles, helicopter, kevlar, email, blackberry, ******* (ha!)....
I would like to suggest that instead of producing heavies, production of the Mossie so that if lost, only 2 crew gone, rather than 7. 3 times the number of aircraft so perhaps equivalent bomb load per target. I only wish the RAF had been as effective as the Germans in attacking night bombers, so huge numbers of intruders to catch the nightfighters taking off to intercept the bombers.
I can't see that we had any real alternative means of attacking Germany apart from the air and daylight attacks were almost suicide.
There was no practical alternative, nor any means of damaging enemy production but by dropping hundreds of bombs around the target area.
That tied up troops and equipment that would have been available elsewhere to the detriment of the Desert campaign and Russia might have been knocked out again. it also hampered production of existing equipment and prevented the design and use of many more effective aircraft, tanks and other equipment. Germany fought practically the whole of WW1 outside its territory, and practically the same in WW2.
I think the one thing I would want the power to change would to have been in the Comet design team and insisted on oval windows, not rectangular.
Aviation might then have seen Britain at the forefront of civil and military design....
