Brig Gen Vicherek was stuck in France until 27 June and did not reach Britain until 7 July.
Hence for a fortnight Janoušek was the most senior Czechoslovak Air force officer in the United Kingdom.
There was not yet a military agreement between the Czechoslovak government-in-exile and the UK, but Janoušek secured the help of the UK's former air attaché to Prague, Wg Cdr Frank Beaumont.
It was agreed that all Czechoslovak airmen could enlist in the RAF Volunteer Reserve and that air force units of Czechoslovak personnel would be formed under RAF command.
An Inspectorate of Czechoslovak Air Force was formed on 12 July 1940.
The UK War Department gave Janoušek the rank of Air Commodore, effectively giving him oversight of all Czechoslovak units of the RAF.

However, the Defence Ministry of the Czechoslovak government-in-exile did not confirm Janoušek's appointment until 15 October 1940, followed by a Presidential Decree to the same effect on 18 June 1941.
Both President Beneš and his Defence Minister, Brig Gen Sergej Ingr, criticised Janoušek for securing an agreement that excluded the government-in-exile from any control over Czechoslovak units and personnel in the RAF.
It also excluded Brig Gen Vicherek from the chain of command.
But it also ensured that the RAF enlisted, trained and equipped 88 Czechoslovak fighter pilots in time for them to fight in the Battle of Britain, including No.
310 Squadron RAF which was the RAF's first squadron formed almost entirely of Czechoslovak personnel.

As Insepector of the Czechoslovak Air Force, Janoušek too was outside the RAF's immediate chain of command.
His job was to inspect the RAF's Czechoslovak squadrons, organise training, propose which Czechoslovak officers should be promoted to command those squadrons, and have meetings with the President Beneš and Defence Minister Ingr.
In the course of the war the Air Force Inspectorate expanded to include other functions including medical, transport and pastoral services.
For a time Janoušek's chief of staff was Wg Cdr Josef Schejbal, who in 1941 commanded No.
311 Squadron RAF, the RAF's only Czechoslovak heavy bomber squadron.

By May 1941 the RAF had up to 1,600 Czechoslovak personnel.
Nos.
310, 311, 312 and 313 Squadrons were almost entirely Czechoslovak, as was one flight of 68 Squadron.
There were also numerous Czechoslovak personnel serving in other RAF units.

On 31 December 1940 the New Year Honours list announced that Janoušek was to be made a Knight Commander of the Order of the Bath (KCB).
HM King George VI knighted him at Buckingham Palace on 20 May 1941.
The BBC broadcaster John Snagge interviewed Janoušek for The World Goes By programme, which was broadcast on the BBC Home Service on 8 July 1941 and the BBC Forces Programme two days later.
Janoušek told BBC listeners:
This anniversary gives me a welcome opportunity to say thank you to Britain and the British people...

The kindness of your RAF officers and men, and indeed of everybody here, has strengthened our souls to carry on.
We have been here one short year.
The qualities which make life worth living – liberty, decency, kindness and common sense – they are so evident here and more than ever we realise their value.
May I thank you on behalf of our Air Force for the privilege of sharing these things with you.
May this next year bring us nearer to victory over the enemy – the enemy not only of (the) British or Czechoslovaks or of any other people, but the enemy of all good.

By July 1941 Janoušek was an Air Vice-Marshal.
His duties as Inspector took him everywhere that Czechoslovak RAF personnel served or trained, including Canada, the US and The Bahamas.
He was a delegate to the December 1944 Chicago Convention on International Civil Aviation that led to the creation of the International Civil Aviation Organization.
On 17 May 1945 Janoušek was promoted to Air Marshal.

Janoušek wrote a booklet in English, The Czechoslovak Air Force.
It is undated but seems to have been published before the end of 1942.
In it he summarises the history of the force from the foundation of Czechosl
