Barnes Wallis is killed during World War One

What if Barnes Wallis was killed during World War One . How would that effect the period up to 1979 when he died in the original time line.
 
No geodetic airship/aircraft construction - so no R101 (I think I'm right there), no Vickers Wellesley, Wellington, or Windsor (no production order), and no bouncing (dambuster) bomb, and no Tallboy or Grandslam!
Probably the lack of the specialist bombs would have the most impact (pun intended).

I think you mean no R100. That was the privately built airship that used Barnes-Wallaces geodesic airframe. The R101 was its government built rival.
 
Life would still go on. The R-100 wasn't built with a geodetic airframe, like the MacMeecham and Schutte-Lanz L.1. They weren't built with "geodetic" construction either, being just called "diamond lattice" since the term hadn't been in vogue yet. The R-100 was ring and girder construction with geodetic re-enforcement for the pendulous bits. I keep raccoons out from under my rear deck with a geodetic diamond lattice in honor of Wallis. I once saw an ultra-light aircraft that looked like a Piper Cub with structure made from what appeared similar to popsicle sticks in geodetic form, but I only saw one. The world would survive without the Wellesley, which carried a bomb load in panniers under the wing because they weren't sure how to build a bomb bay in the fuselage. The Wellington was a good medium bomber, but was it good because of, or in spite of geodetic construction? When tested as a glider tug, they stretched, and when converted to a post-war transport they reverted to a monocoque fuselage for the Viking/Valetta. The Windsor did nothing but show that there was a scale limit to geodetics, and that was the Warwick. The dam-buster bomb was ingenious and a media sensation for morale, but didn't achieve a change in the war, gaining a moderate but temporary gain with heavy expenditure and loss. The ship-busting bouncing bomb never achieved a trial by fire, and was thus a waste of effort. The heavy penetration bombs were something else again. If not for Wallis, is it never thought of, and accomplished?
