If it hasn't already been done, maybe you could patent/copyright it and charge them royalties to use it.

How do emission free electric engines propel a cargo carrying airframe at 0.7 mach at 35,000 feet ? Logistical systems today are partially dependent on vehicles that can carry roughly 200,000 lbs a distance of 3,000 miles at 450 miles per hour, or better, through the air. It has taken us about 100 years to develop this ability. How long will take to replicate current aviation technology with emission free electric powered freighters ? Or do we have to alter our distribution requirements and methods ?

In the video it seems that No 1 (Port Outer), not No 2, received significant damage. An object of considerable size appears to enter the nacelle.

Grade crossings here in eastern PA have an identifier and an 800- number visibly posted on a pole. The 800- number goes straight to the Dispatcher. One night I and several others were waiting at a crossing in Columbia PA,alongside the Susquehanna River, which crossing was blocked by a long, stopped, Norfolk Southern coal train. I phoned the 800- number and the person at the other end apologised and a few minutes later the train moved down the line, clearing the crossing. I don't know if they have the same procedure in other places, but you may check for such a post on crossings. It seems to me very desirable to have some method of quickly alerting the nearest Dispatcher for an emergency situation, such as a stuck vehicle or trailer at a crossing so that signals or radio can be used to stop traffic on the rail line.

Highflyer Thanks for the reply and clarification/confirmation that the crew do conduct a departure briefing. I am however insecure about the auto braking and other automated functions such as callout of runway remaining. In my opinion the more automation, the less the crew are forced to pay attention which can lead to a lag in response or even lack of response. In the really good old days of one of my first flights as a child passenger I found out that the bottom rear corner of rectangular windows on DC3 (passenger aircraft) leak when they fly through rain. Thanks again and all the best for the New Year.

Way back in the old days (1970s) I was lucky to be allowed in a jumpseat. The chap in the right seat called "V1", and then "rotate" (VR), while the chap in the left seat did the flying. I was assuming this was still done. I didn't realise that now the computer does this. Who now handles the braking if an engine fails before V1, or decides when to rotate if it fails after V1 ? Does the computer now do this ? Can a computer handle asymmetric thrust ? If a human does this who is monitoring the airspeed and how long does it take for a human to recognize the engine failure and to take over from the computer ? Under recommended CRM procedures should the captain and first officer discuss and decide all this before they start to roll ?

Thanks for the reply. I had not read the details in the FAA reports which was why I said "superficially". But the summary on 5G I had read just seemed to speak of a problem with altimeters, not with other gear and did not mention that 5G emissions were bleeding into other frequencies. I was under the impression that the FCC would not permit equipment to emit that type of interference. I do realize that with the limited range of C-band signals that many more towers will be needed and that they might also be needed inside airport perimeters and buildings to maintain 5G cell phone coverage. That said, and the reason for my bringing up Musk's SpaceX-Starlink within this context, is that we appear to be creating extensive systems, in this immediate case 5G, which potentially interfere with other existing important uses. But we go ahead and create the new system without considering or addressing the impact of such interference until the new system has been created and almost imple

Its not just things like 5G towers (which are static and somewhat visible) but we don't seem to worry about the possible consequences of Elon Musk's SpaceX Starlink cluttering up "Space" with, initially, 1,700, and ultimately 30,000, more satellites. In addition to their physical presence and impact on astronomy, how much RF are these things going to be pumping out ? What happens if China, or Russia or someone else like India, or all of them, then decide they want to build a similar system ?

Superficially it seems that using 3700-3800 Mhz is still far enough away from 4200-4400 Mhz to preclude interference and I don't see there being any problem with harmonics. Even the top end of the new 5G spectrum - 3950 Mhz still seems usable without problems at 4200-4400 Mhz, especially as cell signals seem to be quite clean and precise.

VNBR looks like a neat little VFR only strip in a bowl in mountains with extremely limited facilities, even to tie down. There is an interesting video of two departures on Youtube. The second one sits on the brakes and winds it up and still uses a lot of concrete. Then he has an interesting climb out but the video seems to cut away too early. I would have liked to see how he got over the mountain, or if he turned right and went through the pass. www.youtube.com/watch?v=BgUJW5M6RWE
