I found this article today on British Newspaper Archives

See the 3rd Paragraph from the end?

Any idea of who this could be ?

"and the navigator of a British bomber. The bomber had come down in flames, and this airman's parachute caught fire. He smothered the fire with his hands. He was returning to England with a wounded head and in injured hands. "

Would be lost in Holland prior to May 12th 1940

Adventurous Escape From Holland
REFUGEES' FLIGHT DURING AIR BATTLE
Three refugees from Holland reached Ealing on Sunday, after a thrilling escape from their home at The Hague. They are Mr. and Mrs. Robert Grimmond and their son. Mr. Grimmond, who is a British subject, has been in business ip Holland as an importer of British engineering products for the past twenty years. He married a Dutch lady. He and his family are staying for the present with Mr. Grimmond's sister, Mrs. G. Craven, of 33. Ravensbourne-gardens, Ealing. Mr. and Mrs. Grimmond told a " Middlesex County Times" reporter how they were awakened at 3 a.m. on Friday by the sound of aeroplanes. They stood for about an hour on a balcony of their house, which is near the airport at The Hague, watching German aeroplanes flying over and listening to the anti-aircraft guns. They did not realise that Holland was at war. They thought the aeroplanes were passing over Holland on their way to England. Then they saw a British aeroplane. They went downstairs and turned on the wireless. Police notices were being broadcast. and among them was a warning that German parachute troops had landed at Delft. Delft is between The Hague and Rotterdam, the nearest big port. They had to reach Rotterdam.
"HAPPY DAYS"
After breakfast they got the car out. The main road between The Hague and Rotterdam was blocked with great drainpipes across it to prevent aeroplanes landing. They had to take a roundabout route in the little roads between the farms. On the way they were continually stopped by Dutch soldiers, who inspected their papers. One of these soldiers, seeing the 'British passport, called out " Happy days!" as they drove off. At Rotterdam, they were sent from the British Consulate to the Seamen's Mission and from there to the dock, where they could see a ship waiting, the Malines. They spent the whole day on the boat, waiting for darkness. German planes came over, twelve or fifteen at a time. Mr. and Mrs. Grimmond saw British and Dutch planes attack them, and they saw one British aircraft go down in flames. Every now and again they were sent below. About a quarter of a mile up the river Maas, a Dutch gunboat was firing on German troops on the opposite bank. The refugees saw a German aeroplane try to bomb it. The bomb only just missed: it fell between them and the gunboat.

PERILOUS VOYAGE
Before they sailed the captain told all the passengers that everybody who wanted to go to England did so at his own risk. It was known that mines had been dropped in the waterway leading to The Hook of Holland. In the ordinary way boats went down that waterway slowly, and with a pilot. The Malines bolted down it at full speed, in pitch dark and without a pilot. There was one anti-aircraft gun at the stern of the boat, but on its way in to Rotterdam an essential part had been taken out at The Hook. Holland had interpreted neutrality so strictly that no armed boat was allowed into Rotterdam. The captain did not have time to pick up the gun part on his way out, so the Malines crossed to England unarmed. Two thanksgiving services were held by clergymen among the passengers on the way to England.
On the boat were Dutch people, Belgians, Norwegians, an Englishman who had lived in Holland for forty years and who had no friends in this country, and the navigator of a British bomber. The bomber had come down in flames, and this airman's parachute caught fire. He smothered the fire with his hands. He was returning to England with a wounded head and in injured hands.
There were about 250 passengers on the Malines. When they reached Gravesend, they were asked for their tickets. They had none, and they had no English money. The ticket collector finally counted them all through the barrier and said, shall charge it up to the Admiralty.'
Mr and Mrs. Grimmond could bring very little luggage: they had left almost everything they possessed. " I haven't even got a toothbrush." Mrs. Grimmond said, and then, with the first sign of bitterness either of them had shown, she said, "It is wicked, wicked to destroy our Holland."
