Now, can the SBug do that?

:doh: How could the VTO be left out!? :roll: Added video URL F-35B VTO test page so new 173 page PDF attached below.

NOW A NEWER LESSER PAGED PDF IS ATTACHED BELOW WITH INFO ABOUT VTOs....

Went alookin' for 'vertical take off' in these pages to see if that page/pages wuz in the PDF so... uhOH more pages....

:devil: I wonder if a 'flying backwards at '30 cannots vertically challenged takeoff' was tested? :drool:

Can the F-35 VTOL?

F-35B performs first vertical take-off
13 May 2013 Dave Majumdar

"...The US Marine Corps' short take-off and vertical landing variant had a requirement to perform vertical take-offs right from the outset of the JSF programme. However, the capability is not emphasised because the F-35B would not be able to carry a tactically significant payload in that configuration....

...Although the Harrier is often touted as a vertical take-off and landing machine, it flies a similar short take-off and vertical landing profile for the overwhelming majority of its missions.

The original X-35B prototype demonstrated the ability to take off vertically in 2001."

Video of the X-35 performing a VTO:

@ 0:37

Take an F-16, stir in a little A-7, bake, then sprinkle on a generous helping of F-117. What do you get? An F-35.

Here is the video I recalled.

Nice shot of Dr. Bevilaqua @ 0:15.

I believe this was video of the very first VTO by the X-35.

Actually the LSD might be better than the LPD for that embarrassing moment when the engine/fan breaks down and you can't take off. Stuck on deck with no maintenance, no VTO. At least the LSD has a well positioned crane for unceremoniously getting you back on the LHD, and your buddies back in the squadron change your call sign to "Crane," and you have to lie that, "It's about the bird... no ... really .. we were .. um in Florida .. I survived a bird strike , yeah that's it .."

Editing a PDF to get it under the limit here can be a barrel of fun so that is why there are now fewer but gooder pages.

In the second X-35B vertical takeoff video the commentator says the aircraft has yet to demonstrate the transition. So now we know where the erroneous idea the F-35B can VTO but not transition from STOVL to conventional flight comes.

SHORT TAKEOFF & VERTICAL LANDING (STOVL) [including VTO]
The F-35B continued sea trials last summer aboard the USS Wasp (LHD 1). Lessons learned from the previous ship trials in 2011 were incorporated and evaluated. Centerline tracking during short take-offs (STOs) was drastically improved with the combination of an improved NWS schedule and the use of the Three-Bearing Swivel Nozzle (3BSN) for yaw control....

...The F-35B STOVL envelope expansion continued last year. The Rolling Vertical Landing (RVL), Creeping Vertical Landing (CVL), Vertical Landing (VL), Slow Landing (SL), Short Take Off (STO) & Vertical Takeoff (VTO) envelopes were all expanded....

...SL and STO testing included crosswind expansion out to 20 knots, completed primarily at Edwards Air Force Base and NAWS China Lake during a wet runway and crosswind detachment. STOVL formation testing began this year, which included formation STOs & SLs. VTO expansion occurred concurrently with soil AM2 soft pad certification....”
