This species has a wingspan of 50 mm and the holotype provided from Tonkin.
In 2013 WingSpan Theatre produced her newest work Lydie Marland in the Afterlife to critical applause.
Higher oxygen concentration (and accompanying higher atmospheric pressure) enabled energetic metabolic processes which encouraged evolution of large land-dwelling vertebrates and flight, with the dragonfly-like Meganeura, an aerial predator, with a wingspan of 60 to 75 cm.
At the 1991 World Gliding Championships in Uvalde, Texas, the trophy for the highest speed went to a winglet equipped 15-meter class limited wingspan glider, exceeding the highest speed in the unlimited span Open Class, an exceptional result.
Rotor diameters are comparable to the wingspan of a Boeing 747.
The wingspan was shortened from the standard 32 ft to 23 ft, a 125 h.p. Warner Scarab was installed and fairings and wheel spats added.
Its wingspan is around 17 mm and its larvae feeds on Verbenaceae species, including Stachytarpheta urticifolia.
From reviewing the evidence, the bird was most probably the émerillon, with the pieds jaunes being either migrant falcons (the only species that might occur in the area, the Sooty Falcon, Eleonora's Falcon and the Peregrine Falcon, are larger than F. duboisi was, if not in overall length, then at least in wingspan) or the juveniles of the marsh harrier, which are distinctly colored and also have yellow feet.
During the 1955 Farnborough Airshow he barrel-rolled a Vulcan at the top of the post-take-off climb, although safe it was a spectacular manoeuvre in an aircraft weighing 69 tons and with a 99-foot wingspan.
The sheep moth has a 5.5-8.5 centimeter wingspan and a relatively slender body and (FW) wings that pink with a yellow streak in the middle and (HW) yellowish with variable black markings with an all-black form near Mount Shasta.

The sixth aircraft, built for the 1912 British Military Aeroplane Competition was noticeably different, with side-by-side seating for its two crew, a shorter wingspan (35 ft (10.67 m) rather than 47 ft 6 in (14.5 m) for the earlier aircraft), while a 70 hp (52 kW) Viale radial engine was fitted.
The Zone-tailed is comparable in length and wingspan to common large Buteos found to the north such as Swainson's and Red-tailed Hawk, but may weigh considerably less.
