1932 French Grand Prix

German racing driver Rudolf Caracciola attends to his Alfa Romeo Tipo B during the 1932 French Grand Prix held at the Reims-Gueux circuit on July 3, 1932.

The field was composed of 16 entries, all Alfa Romeos and Bugattis. Only 3 of the Alfas were Tipo B and they swept the first three places. Rudolf came in third.

Labels

Plants with Labels

Went for a three mile walk yesterday, first time to cover that much distance in several years (two? five?). Guess my body has recovered from the two surgeries I had this year. Anyway, out walking and I notice all these little signs with the names of the plants. I have never been very good with plant names, most of them just sound like gobble-de-gook. Somebody went to a lot of trouble to label these plants. Unfortunately the sun has bleached out much of the writing. Still, a good effort.

DARPA Heavy Lift Challenge

Katana Drone

Defence Blog reports:

Katana carried a 112 pound payload aboard a 29 pound airframe, producing an official payload-to-aircraft-weight ratio of 3.84 to 1, Avidrone said. The Defense Advanced Research Projects Agency had set a 4-to-1 ratio as the goal when it opened the competition in November 2025, a mark no existing heavy-lift drone had reached and one no team in the competition managed to hit. Avidrone’s result was the closest.

This might explain why helicopters with tail rotors are the most common helicopter configuration.
