Boeing (BA) successfully conducted the first of its 787 Dreamliner test flights today, landing without incident after a little more than a 2-hour flight at 2:20pm PST in Washington.

    I re-established my full position last week;
    saw a JAL dreamliner takeoff from San Diego; next day they announced their trial resumption.
    Remodel of 737s and new generation "plastic" 737s is enough to hold this position, for me.

    What "plastic" 737? 737 MAX is not plastic.

    "saw a JAL dreamliner takeoff from San Diego"

     

    Really? Impossible without FAA approval. Boeing's flight was explicitly approved by FAA.

    All plastic 737 ? there is No composite equipents for commerail aircraft in Wastingtion, state Everett or Renton or Auburn
    only, Japan, Kansas and south Caroline for the 787
    Compoiste for the 777-x is still TBD
    Builing aircraft out of composite is a slow process and compoiste barrel section are hard to repair
    miltary aicraft uses composite panels installed on to metal frame

    A two hour test is not long enough nor did the test show how many of the onboard systems were active. A six hour test with most of the onboard systems running would reveal a better result of battery status and whether they can endure the power demands without overheating or overcharging.

    The batteries are not used in flight. They are used as backups on the ground and for starting up things.

    If they were only used on the ground why would they heat and smoke while in flight which is why the 787 was grounded?

    "landing without incident" - so what!! They test flew this bird for several years without anything that bothered them. Big deal. They need to stress test these things - over charge, over temp. stress. They have big f'nen cells butted up against each other without inter-cooling. If there's dielectric (separator) breakdown in one cell, it runs away, overheating adjacent cells especially if charging current is active (likely since the voltage is now lower) and you have a mess. I hope their steel box band aid with some vents makes folks fell OK flying in this thing, but I think I'll pass. Just put NiMH in there and admit you f'd up!

     

    I'm short BA.

    It's just a battery.

    I followed today's test flight on flightaware.com. Plane took off from Payne field and flew west out the Strait of Juan Defuca, then down the coast and made it's usual 180 degree turn right over where I live in Newport, Oregon. Then back north along the Oregon / Washington coast. Turned back toward Everett, then made another loop out the Straight and back to Payne field. I actually saw the plane on the runway via the Payne Field web cam on landing. The flight profile as far as direction, altitude and speed looked totally normal as compared to previous test flights. Glad to see the beautiful bird back in the air. I'm still expecting 90+ share price by summer.
