Please bear with me; it's a long story. This aircraft is currently undergoing reconstruction. The nose section is from 44-85813, an aircraft used as an engine testbed by Curtiss-Wright. This aircraft, civil registration N6694C, crashed in 1980 - registration cancelled. Major parts of another B-17, one used for atomic tests in Nevada, 44-83722 are being used; its civil registration, N3154S, is being adopted but will now be associated with 44-85813.

This experiment brings together NWS forecasters and researchers to evaluate and provide feedback on the concept of allowing warnings to be extended in time and area, a first step towards Threats-In-Motion (TIM) for severe weather warnings for hail, wind, and tornadoes. To facilitate this evaluation, forecasters use Hazard Services Convective to create and manage TIM warnings. The concept and software is tested on several archived cases.
MRMS HMT Hydro Experiment
The Multi-Radar Multi-Sensor (MRMS) Hydrometeorology Testbed - Hydro (hereafter denoted as HMT-Hydro) experiment is a part of the United States Weather Research Program (USWRP) through the Hydrometeorology Testbed (HMT) that runs from 25 June to 20 July 2018. During the HMT-Hydro experiment, forecasters and hydrologists from the National Weather Service (NWS) will work with National Severe Storms Laboratory (NSSL) research scientists to assess new technology and techniques to improve the prediction and warning of flash flooding. In particular, NWS participants will evaluate new probabilistic hydrologic modeling concepts and output within the Flooded Locations and Simulated Hydrographs (FLASH) system that could help convey the uncertainty of the flash flood threat. NWS participants will also evaluate high resolution precipitation forecasts from the NSSL Warn-on-Forecast (WoF) project and the addition of these forecasts into the FLASH system. Feedback from participants will allow NSSL research scientists to identify how these precipitation forecasts could influence the warning decision making process, including the potential for increased warning lead time. The HMT-Hydro experiment runs in conjunction with the Flash Flood and Intense Rainfall (FFaIR) experiment at the Weather Prediction Center (WPC) to collaborate on the short-term forecasting of flash flooding for both a national and regional scale.

Modified P-3 Orion testbed flown for the Naval Research Laboratory returning to Point Mugu following several hours offshore - worth the wait.
Fokker F-VIIa was taken up by KLM on 16 August 1927, which was rebuilt using parts of the H-NADZ. Construction number 002 refers to the technical & engineering department of the KLM at Waalhaven airport in Rotterdam.
This aircraft was used as test bed of engines, like above picture shows the engine of Carley-Werkspoor Jumbo. That construction was started in 1929, on July 26, 1930, while on November 20, 1930, the sole Carley Jumbo was registered to KLM as PH-AFI. However, service operations were delayed due to overheating problems, as originally, the engine was almost completely enclosed to reduce drag as much as possible. After much experimenting the aircraft appeared in early 1931 with an open cowling, baffle-plates and cooling vents on each side of the engine.
Reregistered as PH-ADZ on 28 February 1929 and finally cancelled on 16 September 1938.
Following the end of World War II, the United States began a program of studying supersonic flight, with the program being run in conjunction with the National Advisory Committee for Aeronautics, the US Navy, and the US Army Air Force (soon to become the US Air Force). While Bell Aircraft built the X-1 for supersonic flight, Douglas worked on the D-558 series with much the same purpose. The company began with the D-558-1 Skystreak, which was intended to study both jet propulsion and supersonic speeds; the X-1 broke the sound barrier first, and the Skystreak, while providing valuable research on near-supersonic speeds and handling, could only reach the very beginning of supersonic speed in a dive.
Douglas had intended to equip the D-558-1 with a mixed jet/rocket propulsion, but the fuselage was too narrow. As work began to rectify this problem, Douglas’ designers learned of wartime German research into swept wings for better handling at high speeds. The Skystreak was completely redesigned into the swept-wing, larger D-558-2 Skyrocket. To test the aircraft, the first of three D-558-2s was equipped with only a jet engine, and first flew in February 1948, with rocket propulsion to be added later.
The D-558-2 was intended to only research the effects of supersonic flight on control surfaces and how to counter any problems caused by high speed on manuverability. The D-558-2 reached Mach 1.88 and 74,000 feet in its first series of tests, flown by Douglas test pilot Bill Bridgeman; afterwards, most test flights were either undertaken by US Marine Corps test pilot Lieutenant Colonel Marion Carl (one of the highest-ranked Marine aces of World War II) or NACA’s chief test pilot, Scott Crossfield.
The test program was very successful, discovering many of the difficulties that future pilots would encounter in supersonic environments, and how aircraft designers could plan and rectify these problems. Some Skyrocket flights were flown with dummy drop tanks and bombs to test how ordnance would react at high speed; others had different wing additions, such as leading-edge extensions, slats, movable stabilizers and wing fences, to best learn the effects of supersonic airflow over wings. Only reluctantly did NACA allow the test pilots to try and set speed records, preferring to leave that to the X-1 program and the USAF, but eventually relented. Crossfield took the D-558-2 over Mach 2 on 20 November 1953, the first person to do so.
The D-558-2 program ended in August 1956, after over a thousand flights without a single accident. All three aircraft were preserved for museums, where they remain today.
The first of the D-558-2s built, Bureau Number 37973 is known better as NACA 143. It was delivered in December 1947 with only jet propulsion, to test its handling, and took off and landed conventionally. Once the concept was proven and the other two Skyrockets were available, NACA 143 was returned to the Douglas factory and converted for air-launched rocket tests; in the end, only one of these type of missions were flown before the D-558-2 project ended. NACA 143 was then used as a traveling recruitment tool at airshows for the US Navy, until it was donated to Planes of Fame in 1966.
I suppose not too many people can say they've seen two D-558-2s in 12 hours, but that's what my friends and I did in May 2021. (It's probably not a priority, but when you're aviation geeks...) We saw this first Skyrocket at Planes of Fame, then drove up to Lancaster, California and saw the third and last ever built. Since I had seen the second, record-breaking D-558-2 at the Smithsonian in 2013, this "clinched" the aircraft for me; I've now seen all three Skyrockets.
Like a lot of pictures I took at Planes of Fame in 2021, this was not the best shot in the world, but the museum had been forced by coronavirus restrictions to crowd their aircraft together.

Air Stars,
RA-76490,
Ilyushin Il-76T (c/n 093416506, f/n 1307).
Caught taxiing to the ramp, this Candid has an interesting history. She started out live in April 1979 as an Il-76M with the Iraqi Air Force (Iraqi A/w) as YI-AKO, before returning to Russia in 1998 to be used as an avionics testbed by NPO Vzlyot, where she was designated an Il-76-11. She was later demilitarised and converted to a standard T model before flying with NPO's "airline" Elf Air and then Air Stars in 2001.
In 2003, RA-76490 was ferried to Changchun-Dafangshen, China, where the cockpit section was cut off for use as a simulator and the rest used as a ground instructuional airframe by the Aviation University of the Chinese Air Force at Changchun-Dafangshen.
