Una nube sobre la seguridad de los aviones

PRINCETON – Cuando los aeropuertos en toda Europa reabrieron después de haber cerrado por la erupción del volcán,Eyjafjallajökull, en Islandia, no fue porque haya descendido el nivel de cenizas en la atmósfera sino porque se había revaluado el riesgo que la ceniza suponía para la seguridad de los aviones. ¿Era nueva información científica la que había llevado al levantamiento de la prohibición de vuelos? ¿O se debió a las dificultades personales y económicas que la prohibición estaba causando?

Durante seis días se cancelaron aproximadamente 95,000 vuelos, con un costo para las aerolíneas de más de mil millones de dólares. Se estima que 5 millones de personas quedaron varadas o demoradas. La economía británica perdió 1.5 billones y otros se vieron afectados de manera similar. Los productores de flores en Kenia, que dependen de la transportación aérea para llevar su producto de corta duración a Europa, de repente se quedaron sin ingresos. Dieciséis enfermos de cáncer que necesitaban urgentemente trasplantes de médula ósea estuvieron en peligro porque no podían enviarse por vía aérea las médulas aptas para el trasplante desde los Estados Unidos o  Canadá.

En el pasado, los aviones que han volado entre cenizas de volcanes en los Estados Unidos, Indonesia, Filipinas y México, han perdido temporalmente potencia en el motor y en un caso, cayeron miles de pies de altura, aunque todos lograron aterrizar a salvo. No obstante, no había evidencia de que las cenizas esparcidas más ampliamente sobre Europa desde Islandia provocarían problemas similares. La decisión de detener los vuelos estaba basada en la opinión de que cualquier nivel de cenizas en la atmósfera suponía cierto riesgo para las aviones y que no importaba cuán pequeño era el riesgo, el trabajo del gobierno era, como lo señaló el primer ministro, Gordon Brown, “asegurarse de que lo primordial era la seguridad.”

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
