  1. What's flying over your house? Thread #2

    At my daughter's house in Brighton, Saturday I saw a Dragon Rapide fly over, heading West. Just now, at home a very fast Typhoon departure, sounding like a max performance training run. Or a scramble.
  2. Lightning F6 (classing this one as finished for now)

    Thanks for that chaps. Hmm - so maybe my (now rather old) model of a Firebird's Lightning 1a in a fast climb out with all the gear coming up and take off flaps still set may be wrong. Drat. I do recall a comment about the max speed for gear retraction completion was quite challengingly low in some circumstances.
  3. Lightning F6 (classing this one as finished for now)

    Superbly done. One minor question - would the noseleg not also be well on its way up by this point? My recollection of Lightnings was that as the main gear folded away the noseleg typically was also folding forward. Or was that dependent on the hydraulic set up and 'stiction' of an indivudual aircraft's systems?
  4. someone give Airfix Workbench a dictionary

    'Nice' was a fine word, now destroyed by overuse. Something being a nice fit MEANT something once ! No, the OP was not being a pedant - except in the most complimentary sense.
  5. October 2017 SAMI Magazine

    I believe some computer problems may have exacerbated this. Many of us are vulnerable to that !
  6. Sea Hornet to be returned to flight!

    What superb news . A most beautiful aircraft. Whee !
  7. What an interesting topic, which has wandered intriguingly at times.I still buy some modelling magazines - most;y SAM for old times' sake and because I too like Gary Hatcher's amusing and quaint writing style. Some random comments - Actually Dave, I think there were five nots in the sentence you commented on... ('Pedants are us', alive and well up North!) Terrific to see John Aero back on line. Folk remembering Airfix Series 1 for 2/-. Happy days. I seem to recall they were 1/11 in Woolies, 2/11 for Series 2. That one penny difference in price was worth while then ! I could rarely afford anything from the higher number series except at birthdays & Christmas. Conversions prompted by Alan Hall and (more rarely) by W R Matthews in Flying Review - all done in balsa with much sanding, talc, doping etc. I have a vague memory using banana oil, but maybe that was for flying models? And plunge form moulding, which took lots of practice and some times upset my mother when I made a mess in her kitchen. John B
  8. New Gliding World Altitude Record

    I recall a Canadian friend who told me their drill in the event of engine failure in the CF-104 was to pull up immediately while trying the relight procedure. If you hadn't got a relight by the time the aircraft was dropping back down through 10,000ft, you ejected. That saved a few Canadian crews. Malpaso, I agree it wasn't the ideal machine for low level reconnaissance or attack, though it did surprisingly well at that. For Germany, leaving complex machines with sensitive electronics out in Northern European conditions didn't help their serviceability. Nor did a ten year gap in trained NCOs and maintainers. Some countries had an excellent record with the 104, losing very few. The Lightning had a dreadful accident record overall. Fortunately a rather good ejection seat. It was a complex and awkward design from many aspects - and multiple failures not surprising in such a tight packed airframe. A machine successfully used well outside its original design role, but very limited too. John T - yes, other Cold War machines were notably dangerous to fly. The F-100 and the F-101 come to mind. Brave and determined pilots
  9. XV230 and XV239

    RIP indeed. Two sad events, both so unnecessary. I miss the Nimrods, as do many of us - lovely looking machine, fine sound, very capable platform.
  10. New Gliding World Altitude Record

    Yes. I was most impressed years ago after building their 1/32nd LS-8 to find its wingspan to fuselage length ratio was almost the exact inverse of that of the F-104 - I had a 1/32nd Hasegawa 104G and laid one on top of the other to check !
  11. New Gliding World Altitude Record

    Oh excellent news. Thanks JohnT - I missed that information. This was something that has being worked on by a number of teams, including fairly recently Steve Fosset until his death. I think he was involved in Perlan. Quite a few soaring pilots have flown seasons in Argentina; the wave systems there are extraordinary, though the distances and remoteness makes all these efforts extraordinarily challenging, even before the survival at height issues. A lot of study and thought needed to manage risks reasonably. For along time the height record was limited by the need for a pressure cabin - around 48,000 ft is the unpressurised limit. And as Mike says , the cold as well is a major issue, both for the aircraft structure and the crew. So many problems to solve. At those heights - what is the margin between stall and flutter limits? I see the wing is theoretically good to ~90,000 ft, but how quickly do the theoretical margins reduce? How long would an emergency descent take? What limits on airbrake use and g loading turns? Etc, etc. How high did they need to tow - with those specially designed high altitude optimised wings, lower level soaring may have been hard. What towed them - was it an exciting exercise for the tug pilot? It makes our UK soaring height record of 37,000 ft plus look low - and that was challenging for cold and crew physiological limits. (Set in Scotland some years back, from Aboyne.) I'd really like to know more about what the systems were and what back-ups (if any) they had, so thanks again for the 'nudge'! I bet we don't see a a kit of this for awhile - though maybe Airbus might 'sponsor' it. John B
  12. Float planes and a bear

    Superb. Like Silver Fox, brings back memories of floatplane days. Beavers - superbly versatile and tough ! Thanks

    Most Interesting Rita. Thank you for the detail you have provided. I understand Matthew's concern about instant petitions etc., however I have had some experience of trying to influence 'official bodies'. All too often only a strong indication of public interest has any effect. The folk appointed or who stand for 'public service' rapidly develop very thick skins, even if they didn't have them before hand. That doesn't make listening to other points of view any easier, hence the need for petitions Matthew. Democracy doesn't work well too quietly, and we can't assume those in authority know what they are doing. Examples abound that show they are at least as frequently confused and ill informed as the rest of us. Having read into this one carefully, I will be signing this particular petition. The proposed new works are quite ugly and I haven't seen any worthwhile justification for losing the Vestry or changing the use of the Nave. Fiddling to no real benefit, and arguably to considerable loss. The earlier proposals - which Rita describes as including a 'mini-Duxford' are much more appropriate and sympathetic. Bonnier, too! Regards, John B
  14. I do hope the RAF has properly assessed its refuelling needs for the immediate future. Would be embarrassing to have to hire these back! We have had some rather enthusiastic cutting of capability over recent years- I find it appalling to realise that my Harrier models are of an era now past.
  15. Shuttleworth WW1 evening airshow

    Thank you. John B
