Shares of Airbus Group on Monday dropped after the crash of an A400M military plane that left investors in anxiety over Europe's largest and heavily delayed defense project.

The European multinational aerospace and defense corporation pledged that it will very soon overcome the tragedy.

Shares in Europe's largest aerospace group, which hit a record high in April, fell 3.8% to 61 euros in morning trading.

The military plane crashed outside Seville on Saturday, killing four crew members. The accident prompted Britain, Germany and Malaysia to ground their fleets of Europe's new crew and cargo carrier.

France said that it would keep flying its lanes, whereas Airbus pledged to resume flight testing as per schedule on Tuesday.

As per analysts the crash raised concerns about deliveries and long-term exports of the A400M. Company chief executive Tom Enders reaffirmed the company's commitment to the program as he paid tribute to the crew.

In a letter to staff Enders said, "Testing would resume as planned on Tuesday to demonstrate to our customers, the air forces, that we fully trust this great transport plane and are as committed to the program and the further ramp- up of deliveries and capabilities as ever".

Ender's asked the company's employees to observe a minute's silence at midday for the two pilots and two test engineers who lost their lives.

The men who lost their lives in Sevilla were great professionals, and they knew about the risks of their job and would not want them to stop flying.

The A400M was developed at a cost of 20 billion euros ($22.33 billion) to give European NATO nations an independent access to heavy airlift for military and humanitarian operations.

The European governments injected more money into the project in 2010 after more than three years of delays and billions of euros of cost overruns.
